- Question
A train left from station A for station B at 4 pm at an average speed of 80 kmph. At 8 pm, another train also had left from station A for station B on a parallel track at an average speed of 120 kmph. How far from A is another train expected to overtake the first train?
Options- A. 900km
- B. 940km
- C. 960km
- D. 980km
- Correct Answer
- 960km
ExplanationAns.
Distance covered by 1st train in 4 hours = 80*4 = 320 km
Relative speed of 2nd train = 120-80 = 40 km
It will overtake another train in 320/40 = 8 hours
Distance between overtake point and station A = 8*120 = 960 km - 1. A passenger train running at the speed of 80 kms/hr leaves the railway station 6 hours after a goods train leaves and overtakes it in 4 hours. What is the speed of the goods train?
Options- A. 32 kms/hr
- B. 50 kms/hr
- C. 45 kms/hr
- D. 64 kms/hr Discuss
- 2. A train covers a distance of 12 km in 10 min. If it takes 6 sec to pass a telegraph post, the length of the train is
Options- A. 90 m
- B. 100 m
- C. 120 m
- D. 140 m Discuss
- 3. A uniformly moving train of length 480 m takes 3 minutes to completely cross a platform. If the same train, with the same speed crosses a pole completely in 30 sec, then the length of the platform is -
Options- A. 1 km
- B. 600 m
- C. 4.8 km
- D. 1.2 km Discuss
- 4. Train A takes 1 hour more than train B to travel a distance of 720 km. Due to engine trouble speed of train B falls by a third, so it takes 3 hours more than Train A to complete the same journey? What is the speed of Train A (in km/hr)?
Options- A. 80
- B. 90
- C. 60
- D. 70 Discuss
- 5. A train is moving at the speed of 72 km/hr. How many seconds will it take to cover a distance of 1400 m ?
Options- A. 70
- B. 80
- C. 72
- D. 84 Discuss
- 6. A train travels 40% faster than a car. Both start from point A at the same time and reach point B, 140 km away at the same time. On the way the train takes 25 minutes for stopping at the stations. What is the speed (in km/hr) of the train?
Options- A. 67
- B. 134.4
- C. 145.9
- D. 160 Discuss
- 7. The time for a train of length 110 metres running at the speed of 72 km/hr to cross a bridge of length 132 metres is
Options- A. 9.8 sec
- B. 12.1 sec
- C. 12.42 sec
- D. 14.3 sec Discuss
- 8. Two trains are moving in the opposite directions at speed of 43 km/h and 51 km/h respectively. The time taken by the slower train to cross a man sitting in the faster train is 9 seconds. What is the length (in metres) of the slower train?
Options- A. 235
- B. 338.4
- C. 470
- D. 940 Discuss
- 9. A train 110 metres long is running with a speed of 60 kmph . In what time will it pass a man who is running at 6 kmph in the direction opposite to that in which the train is going ?
Options- A. 5 sec
- B. 6 sec
- C. 7 sec
- D. 10 sec Discuss
- 10. A train is moving at the speed of 90 km/hr. How many seconds it will take to cover a distance of 2275 meter?
Options- A. 96
- B. 91
- C. 86
- D. 93 Discuss

Correct Answer: 32 kms/hr
Correct Answer: 120 m
Explanation:
Speed of the train = 12000 / 10*60 = 20 m/s
Length of the train = Speed X time = 20 X 6 = 120m
Correct Answer:
Explanation:
Let length of platform be ?y?metres.
Then, at the platform,Distance travelled = y + (length of train) = (y + 480)m
Then, Speed of train = (y + 480)m / (3x60) sec = (y+480)/180 ...(1)
Also, at the pole,Distance travelled = length of train = 480m
Then, Speed of train = 480m / 30sec = 16 m/s ...(2)
Equating eq.(1) & eq.(2), we get,
(y+480)/180 = 16(y+480) = 16 x 180 = 2880
y = 2880 ?480 = 2400m or 2.4 km long platform.
