Question

A train travelling at 60 kmph takes 27 seconds in passing a certain point.Find the length of train

Answer 1

Speed of train = 60 kmph

We know that 1 km = 1000 m and 1 hour = 3600 seconds

So, 1 kmph = 1000 / 3600 = 5/18 mps

Therefore, 60 kmph = 60 * 5/18

= 50 / 3 mps

Time taken to pass the point = 27 seconds

Speed = Distance / Time

Distance = Speed * Time (When a train passes a point, distance covered = length of train)

= (50 / 3) * 27

= 50 * 9

= 450 mts

Hence, length of train = 450 mts.
