Question

A train of length 50 m is moving with a constant speed of 30 m/s.Calculate the time taken by the train to cross a bridge of length 0.1 km.​

Answer 1

★ GIVEN:-

• Length of train = 50m

• Speed of train = 30m/s

• Length of bridge = 0.1km = 100m

★ NEED TO FIND :-

• The time taken by the train to cross a bridge

★ SOLUTION:-

• Distance covered by train to cross the bridge

d = 100 + 50 = 150m

• Now, Using Formula

t = d/s

_________________

Where,

t = time

d = distance

s = speed

__________________

t = 150/30

t = 50 sec

• Therefore, the time taken by the train to cross a bridge = 50 second
