What is the length of train? Let the length of the train be L meters Let the speed of the train be V meters per second. Given that the time taken by the train to cross a pole is 10sec Hence the length of the train is given by L=V*10-(1) The length of the platform is 250 meters and the train takes 20 seconds (from the time of the engine of the train enters the platform at one end and the last compartment leaves the station on the other end of the platform), the equation corresponding to this activity can be written as L+250=20*V-(2) Solving equations 1 and 2, we get V=25m/sec and L=250m 136 views Sponsored by Chegg Study® Study time, crunch time, anytime.
