Question
A train moving at 72 km/h takes 20 seconds to pass a
pole. Find the time required for the train to cross a platform that is 0.6 times the length of the train.Solution
ATQ, Length of the train = (72 × (5/18) × 20) = 400 metres Length of the platform = (400 × 0.6) = 240 metres Time taken by train to cross the platform = [(400 + 240) / (72 × (5/18))]= (640 / 20) = 32 seconds
