Answer 2

Concept introduction:

Length of a train is determined by multiplying the speed of the train with the time. After this step, the actual length of the train is determined by substracting the multiplication with the length of the bridge.

Given:

We have been given the speed of the train, the time taken by the train to cross the 100 m long bridge,

To find:

We have to find the length of the train.

Solution:

According to the question

Speed=36kmh −1

=36× 5/18

​ =10ms −1

Length of bridge=100m

Time taken  = 14s

Let the length of the train = x.

∴v= (x+l)/t

​or , x=v×t−l

or , x=10×14=100

=40m

Final answer:

The length of the train is 40m
