Question

A train of length 50 m is moving with a constant speed of 10 m/s. Calculate the time taken by the train to cross an electric pole and a bridge of length 250 m

Answer 1

to cross an electric pole...d=50m(length of train...as the whole train has to cross the pole)s=10m/st=d/s=50/10=5secondsto cross the bridge...d=50+250=300m(length of train+bridge)s=10m/st=d/s=200/10=20second
