Question
A train moving at a speed of 135
km/h takes 6 seconds to pass a stationary vertical tree. How long will it take for the train to completely cross a platform that is 450 meters long?Solution
ATQ, Speed of train = 135 × (5/18) = 37.5 /sec Therefore, length of the train = 37.5 × 6 = 225 metres Time taken by the train to cross the platform = (225 + 450)/37.5 = 18 seconds
