Time, Speed and Distance Tests — Pick a Level and Start
Tap a level to see every test in it. Level 1 is set at real SSC CGL difficulty — start there the day you finish the concept. Level 2 is pitched above the exam, to push accuracy under pressure.
Level 1 SSC CGL Level Checking… View tests
Same difficulty as the real SSC CGL paper — one idea per question, at most two stages. Distance, speed and time with km/h and m/s conversions; clock-time journeys with halts; speed ratios and the inverse time ratio; average speed over equal distances, equal times and a square track; late and early arrivals; a head start in metres or in minutes; two travellers meeting or moving apart; the time after they meet; turn-back meetings; buses met on the road; trains passing poles, people, platforms, bridges and other trains; stoppage minutes; wheel turns and clock hands; echoes and rail clicks; and walking inside a moving train. A steady score here means the chapter is exam-ready.
Level 2 Above SSC CGL Level Checking… View tests
Harder than the exam asks, because every question chains two steps or runs one backwards. A chaser who speeds up or halts midway; a thief closed in from both sides; a vehicle that halts before a meeting; a speed found from two what-ifs; a round-trip average speed that leads to a quadratic; stretches linked by length and time; the fraction of a road covered at a meeting; walkers shuttling between two points; buses met in both directions; a train’s length and speed found from two timings, then used again; passengers timing trains from other moving trains; a sound gap through steel and air; and a storm’s speed from two thunder delays. Clear these and the real paper feels easy.
Almost every question in this chapter rests on one line: distance = speed × time. What makes it hard is everything around that line — units that must match, speeds that combine as a relative speed, and lengths that a train has to cover before it is past anything.
The marks are lost in three places. The first is skipping the 5/18 conversion — a 150 m train at 54 km/h passes a pole in 10 seconds, not in 150 ÷ 54 of anything. The second is taking the plain middle of two speeds: going at 40 km/h and coming back at 60 km/h gives an average speed of 48 km/h, not 50. The third is using the wrong relative speed or the wrong distance — subtracting speeds for trains that approach each other, or forgetting one of the two lengths. Each test puts twenty-five time, speed and distance questions in front of you in one sitting, which is what makes those checks automatic.
How Many Time, Speed and Distance Questions Are Asked in SSC CGL?
Time, speed and distance, with trains, is one of the steadier arithmetic chapters in SSC CGL. The questions are short, and most of them test whether you picked the right relative speed and the right distance.
| Chapter | Tier I (out of 25) | Tier II Paper I (out of 30) |
|---|---|---|
| Time, Speed, Distance & Trains | 1–2 | 2–3 |
| Boat & Stream | 0–1 | 0–1 |
| Ratio & Proportion | 1–2 | 2–3 |
Counts vary by shift. Boats, streams and races are built on the same relative-speed idea, so the hour you spend here also pays back in those chapters.
What You Will Practice in the Time, Speed and Distance Chapter
Core topics
- Distance, speed and time with conversions between km/h, m/s and metres per minute
- Journeys read from departure and arrival clock times, with halts on the way
- Speed ratios, and the inverse ratio of times over the same distance
- A speed changed by a fraction, and the minutes saved or lost
- The speed needed for the rest of a trip to finish on time
- Average speed over equal distances, equal times and unequal stretches
- The speed needed on the last stretch to reach a target average speed
- Late at one speed and early at another — distance, on-time speed and clock time
- Two what-ifs about speed and time used together to recover the distance
- Chasing with a head start in metres or in minutes, including delayed starts
- Two travellers meeting, moving apart, or starting at different clock times
- The time each traveller needs after they meet, and the meeting time from it
- Turn-back meetings, where one traveller reaches the far end and returns
- Buses leaving at fixed intervals and how often a walker or cyclist meets them
- Trains passing a pole, a person, a platform, a bridge or a tunnel
- Two trains crossing in the same or opposite directions
- Stoppage minutes per hour, halts on a route and rests along a walk
- Wheel turns and radius, and the distance moved by clock-hand tips
- Walking both ways against riding both ways, and paths at right angles
- Sound, echo, thunder, telegraph poles and rail-joint clicks
- Walking inside a moving train and on moving walkways
Rules worth memorising
| Situation | Rule |
|---|---|
| The basic relation | distance = speed × time |
| Changing units | km/h × 5/18 = m/s; m/s × 18/5 = km/h |
| Same distance, speeds in the ratio a : b | times are in the ratio b : a |
| Equal distances at a and b | average speed = 2ab ÷ (a + b) |
| Equal times at a and b | average speed = (a + b) ÷ 2 |
| Late by x at S1, early by y at S2 | D(1/S₁ − 1/S₂) = x + y |
| Same direction | relative speed = S₁ − S₂; catch time = gap ÷ relative speed |
| Towards or away from each other | relative speed = S₁ + S₂ |
| After two travellers meet | S₁ : S₂ = √t₂ : √t₁; time to meet = √(t₁ × t₂) |
| Train past a pole or a person | time = train length ÷ relative speed |
| Train past a platform or bridge | time = (train + platform) ÷ speed |
| Two trains passing each other | time = (L₁ + L₂) ÷ relative speed |
| Stoppages | stop minutes per hour = (S without − S with) ÷ S without × 60 |
| Wheels and echoes | one turn = 2πr; echo distance = sound speed × time ÷ 2 |
The first three rows carry the chapter. Most of the others are those three applied with the right relative speed and the right distance.
The three mistakes that cost the most marks
- Mixing units. A length in metres and a time in seconds need a speed in m/s. Multiply km/h by
5/18first; leaving it out puts the answer off by a factor of 3.6, and that wrong value is almost always one of the options. - Averaging speeds directly. Average speed is total distance over total time. For equal distances at 40 and 60 km/h it is
2 × 40 × 60 ÷ 100 = 48km/h; the plain middle, 50, is the trap. - Picking the wrong distance or relative speed. Add speeds for bodies moving towards each other and subtract them for bodies moving the same way. A train must cover its own length past a pole, and both lengths past another train.
Solved Examples — SSC CGL Time, Speed and Distance
= 2 × 40 × 60 ÷ (40 + 60) = 4800 ÷ 100 = 48 km/h. Check with a 120 km road: 3 hours out and 2 hours back, 240 km in 5 hours. The plain middle, 50 km/h, is the usual wrong option. Answer: 48 km/h150 + 250 = 400 m. Its speed is 72 × 5/18 = 20 m/s, so the time is 400 ÷ 20 = 20 seconds. Using only the platform length gives 12.5 seconds — a common wrong option. Answer: 20 seconds50 + 58 = 108 km/h = 30 m/s. They must slide past both lengths, 120 + 180 = 300 m, so the time is 300 ÷ 30 = 10 seconds. Using the difference of speeds would give 135 seconds. Answer: 10 seconds10 + 5 = 15 minutes. For the same distance D, D(1/4 − 1/5) = 15/60, so D ÷ 20 = 1/4 and D = 5 km. Check: 75 minutes against 60 minutes. Taking the gap as 10 − 5 is the trap.

How to Prepare Time, Speed and Distance for SSC CGL
- Fix the units first. Decide whether the question lives in km and hours or in metres and seconds, and convert every speed before you use it.
- Draw the situation. A line with two dots and arrows shows at once whether the speeds add or subtract, and what distance has to be closed.
- Name the relative speed. Same direction, subtract; towards or away from each other, add. Write it down before dividing.
- For trains, list the lengths. A pole or a person adds nothing; a platform, bridge or tunnel adds its own length; another train adds its length too.
- Never average speeds directly. Use total distance over total time, or the 2ab ÷ (a + b) short cut for equal distances.
- For late and early questions, add the minutes. One arrival is before the fixed time and one after, so the two walking times differ by the sum.
- Keep halts in the time, not the distance. A stop costs minutes but covers no ground.
- Underline what is asked. A speed, a length, a clock time, the time after a meeting or the distance still to go are all different answers.
- Do Level 1 untimed, the same day you finish the theory. It is set at real SSC CGL difficulty; the aim is picking the right method, not speed.
- Repeat Level 1 with the 15-minute clock on, then move to Level 2. After that, verify against a previous year paper and a full mock test under locked sectional timing.

SSC CGL समय, चाल और दूरी (Time, Speed and Distance) चैप्टर टेस्ट — हिंदी में
इस अध्याय का लगभग हर प्रश्न एक ही सूत्र पर टिका है: दूरी = चाल × समय। कठिनाई इसके आस-पास की बातों में है — इकाइयों का मेल, सापेक्ष चाल (RELATIVE SPEED) का सही चुनाव, और ट्रेन को तय करनी पड़ने वाली लंबाइयाँ।
अंक तीन जगह कटते हैं। पहली: km/h को m/s में बदलना भूल जाना — 5/18 से गुणा किए बिना उत्तर 3.6 गुना गलत आता है। दूसरी: दो चालों का सीधा बीच लेना — 40 km/h से जाकर 60 km/h से लौटने पर औसत चाल 48 km/h होती है, 50 नहीं। तीसरी: गलत सापेक्ष चाल या गलत दूरी लेना — आमने-सामने आती ट्रेनों के लिए चालें घटा देना, या दोनों में से एक लंबाई छोड़ देना।
TrickySSC पर इस अध्याय के सभी टेस्ट हिंदी में उपलब्ध हैं — प्रश्न, विकल्प, विस्तृत हल और शॉर्टकट ट्रिक सब हिंदी में। दो स्तर हैं: लेवल 1 (SSC CGL के स्तर का) और लेवल 2 (SSC CGL से कठिन)। प्रत्येक टेस्ट में 25 प्रश्न, वैकल्पिक 15 मिनट का टाइमर और +2 / −0.5 की वही मार्किंग जो असली परीक्षा में होती है।
