Question
A train takes 57 seconds to cross the 204 m long bridge.
If the same train takes 23 seconds to cross a signal board, tell the length of the train. (In meters)Solution
Let the length of the train be x m. Length of the platform = 204 m As we know, Speed = Distance/time (x+204)/57 = x/23 23x + 4692 = 57x 57x-23x = 4692 34x = 4692 x = 4692/34 x = 138 Length of the train is 138 m.
