Question

A train of length 50m is moving with a constant speed of 10m/s.
Calculate the time taken by the train to cross an electric pole
and a bridge of length 250 m. (5s, 30s) (AS)​

Answer 1

Answer:

The speed of the train is s=10m/s and the distance covered is d=300m. Therefore, the time is taken by the train to cross the bridge and the pole is 30 sec.

Answer 2

Given,

Length of the train = 50 m

Speed = 10 m/s

Length of bridge = 250 m

Distance = 250 + 50 = 300 m

Speed = Distance ÷ time

Time = Distance ÷ speed

= 300/10

= 30 sec
