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

Step-by-step explanation:

The train covers 272m - 200m = 72 m in 23- 19 = 4s.

So, the speed of the train was speed = 72m/4s = 18m/s.

So, the distance that the train covered was 18 m/s * 23 s = 414 m in 23 sec.

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