A 340 m long train crosses a platform twice its length
in 2 min. Find the speed of the train. TYPE 2Solution
Speed of train = (Length of train + Length of Platform)/Required time Length of train = 340 m Crossing time of platform = 2 × 60 = 120 sec Length of platform = 340 × 2 = 680 m Let the speed of train be x. Speed of train = (340 + 680)/120 ⇒  x = 1020/120 = 8.5 m/s
