Question

A train takes 23 sec to past completely through a station of 272 m long and 19 sec to another station is 200 m long. The length of the train is

Answer 1

Answer: 142 m long (I think)

Step-by-step explanation:

It goes 272m and 200m in some sec. So, 272 - 200 = 72 m in 23 - 19 = 4s

SO we know the distance is speed = distance / time; so, 72m/4s = 18s.

The train covers in 23 * 18 = 414 m in 23 sec.

So therefore, length of train is 414 - 272 = 142m.

The train is 142 m long
