Question

The train is traveling at 48 km per h cross 250 m of a platform in 30 s find its length

Answer 1

Length of train = 150 m.

Step-by-step explanation:

If a train crosses a platform, then the distance covered by the train should be equal to the length of platform + it's own length.

Speed = 48 kmph = 48 × (5/18) m/s

speed = (40/3) m/s

Time = 30 seconds.

Distance = speed × time

Distance = (40/3) × 30

Distance = 400 m.

Therefore,

Length of platform + length of train = 400 m

250 + length of train = 400

Length of train = 400 - 250 = 150 m.

Hence, the length of the train = 150 m.
