Question
Gatiman express train crosses a platform in 23 seconds
while it can cross a pole in 10 seconds. If the speed of the Gatiman express is 25 m/s, then find the length of the platform?Solution
Length of the train = 25 Γ 10 = 250 metres Let the length of the platform be βpβ metres ATQ; p + 250 = 25 Γ 23 Or, p = 575 β 250 Or, p = 325
