Question

us pralle is 600 km/hour. How much distance call it
16. A train crosses a pole in 12 seconds. If the length of the train is 120 metres, find
its speed in metres/sec and in km/hour.
​

Answer 1

Answer:

36km/h

Step-by-step explanation:

Okay, so the length of the train is 120m, that means when the first point of the train reaches the pole, it further has to travel 120m so that the last point of the train crosses the pole.

So the distance travelled, d= 120m

This distance is covered in, t= 12sec

So, the speed of the train, v= d/t

=120/12

=10m/s

•°• 10×(18/5)= 36km/hr is the answer.
