A train is moving at a constant speed.
If the train covers 50 km in 2 hours, how much time would it take to cover 100 km?
Given:
Distance travelled in 2 h=50 km.
Speed = DistanceTime .
⇒Speed=502 = 25 km h−1
Now, to travel 100 km at the same speed as given above,
Speed =25 km h−1 =DistanceTime
⇒Time =100 km25 km h−1
⇒ Time =10025=4 h.
