Question

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

Answer 1

length of bridge = 250
length of train = 50m
total distance=250+50=300m
speed=10m/s
time taken=300/10=30s

Answer 2

length of train=50m and length of bridge = 250 m so total distance = 50 +250= 300m and the speed = 10 m per second
so total time = total distance /total speed
300/10 = 30 seconds
