Question

a train 200metres long is running with a speed of 36 km/h. how much time will it take to pass a standing police?​

Answer 1

Answer: 20sec

Step-by-step explanation:

here the train needs to cross the standing police. so, the total distance the train needs to cover is 200m. and given the seed of the train is 36km/hr.

as we know, speed = dist/time

time = dist/speed

time = (0.2km)/(36km/hr)

time = 20sec
