A train running with a speed of 153 km/hr can cross a
pole in 13 seconds and a platform in 17 seconds. Find the length of the platform.Solution
Speed of the train = 153 × (5/18) = 42.5 m/sec Length of the train = 42.5 × 13 = 552.5 metres Let the length of the platform be ‘x’ metres Therefore, 552.5 + x = 42.5 × 17 Or, x = 722.5 – 552.5 = 170 metres
