Answer 2

The length of the train is 200 meters.

Explanation:

Given that,

The speed of the train, v = 20 m/s

It cross a pole in 10 seconds, t = 10 s

We need to find the length of the train. The length of the train is equal to the distance covered by it. It can be given by :

$d=v\times t$

$d=20\ m/s\times 10\ s$

d = 200 m

So, the length of the train is 200 meters. Hence, this is the required solution.
