Question
A train running with a speed of 45 km/hr can cross a
pole in 10 seconds and a platform in 20 seconds. Find the length of the platform.Solution
Speed of the train = 45 × (5/18) = 12.5 m/sec Length of the train = 12.5 × 10 = 125 metres Let the length of the platform be ‘x’ metres Therefore, 125 + x = 12.5 × 20 Or, x = 250 – 125 = 125 metres
