Answer 2

360 m or 0.36 km

Let length of train = x m

Distance covered by train = length of train = x m

(To cross the pole present at the front point of train, the end point of the train must coincide with the pole, which means the train has to cover its own length.)

Speed of train = 108 km/h

= 108 × 5/18 m/s

= 30 m/s

Time taken = 12 seconds

Distance = speed × time

= 30 × 12

= 360 m

Now, Distance covered by train = length of train

So, length of train = 360 m = 0.36 km
