Question
A train is moving at a constant speed of 234 km/hr. It
takes 8 seconds to pass a pole and 18 seconds to cross a platform. Calculate the difference between the lengths of the platform and the train.Solution
Length of the train = 234 × (5/18) × 8 = 65 × 8 = 520 metres Let the length of the platform be ‘l’ metres Therefore, 520 + l = 65 ×18 Or, l = 1170 – 520 = 650 metres Required difference = 650 – 520 = 130 metres
