Question

Two trains are travelling at the speeds of 30 km/hr and 58 km/hr in the same direction. a man sitting in the slower train crosses the faster train in 18 seconds. what is the length of the faster train?

Answer 1

relative speed = 58 - 30 = 28 kmph = 28×5/18
m/s
time taken = 18 sec

length of faster train = 28×5/18 × 18 = 140m

Answer 2

Answer:

To find the length of the faster train you will have to do the following steps :

(28 multiplied by 5 /18) * 18 = 140 m
