Question
A train running at a speed of 60 km/h takes 30 seconds
to cross a pole. Find the approximate time taken by the train to cross a platform whose length is 0.5 times the length of the train.Solution
ATQ, Length of the train = (60 × (5/18) × 30) = 500 metres Length of the platform = (500 × 0.5) = 250 metres Time taken by train to cross the platform = [(500 + 250) / (60 × (5/18))]= (750 / 16.67) = 45 seconds
