Question
A 480 m long train crosses a platform twice its length
in 2 min. Find the speed of the train.Solution
Speed of train = (Length of train + Length of Platform)/Required time Length of train = 480 m Crossing time of platform = 2 × 60 = 120 sec Length of platform = 480 × 2 = 960 m Let the speed of train be x. Speed of train = (480 + 960)/120 ⇒ x = 12 m/s
