Question
A train takes 52 seconds to cross the 204 m long bridge.
If the same train takes 18 seconds to cross a board, then tell the length of the train. (In meters)Solution
Let the length of the train be x m. Length of the bridge = 204 m As we know, Speed = Distance/time (x + 204)/52 = x/18 18x + 3672 = 52x 52x18x = 3672 34x = 3672 x = 3672/34 x = 108 The length of the train is 108 m.
