Answer:
Step-by-step explanation:
A train running at the speed of 60 km/he crosses a pole in 9 seconds. What is the length of the train?
We know Speed = distance/time
Distance = Speed × time
Speed of train =60 km/hr
Time = 9 seconds = 9/3600 =.1/400 hour
Distance = length of the train
Distance = 60 km/hr × 1/400 hour
= 60/400
= 6/40 km.
= 6000/40 metres
= 600/4
= 150 metres.
Answer the length of the train is 150 metres
