Question
A train running with a speed of 81 km/hr can cross a
pole in 13 seconds and a platform in 19 seconds. Find the length of the platform.Solution
Speed of the train = 81 × (5/18) = 22.5 m/sec Length of the train = 22.5 × 13 = 292.5 metres Let the length of the platform be ‘x’ metres Therefore, 292.5 + x = 22.5 × 19 Or, x = 427.5 – 292.5 = 135 metres
