Question

Two trains are running in opposite direction with a speed of 62 km/hour and 40 km/hour respectively. If the length of one train is 250 meters and they cross each other in 18 seconds then what is the length of the other train?

Answer 1

Answer:

The relative speed of train = 62 + 40 = 102 km/h = 102*5/18 m/s = 28.33 m/s

Length of one train = 250 m

Let the length of the other train = x

250 + x = 28.33*18 = 510 m

x = 510 - 250 = 260 m

Length of the other train = 260 m
