If the train covers 50 km in 2 hours, how much time would it take to cover 100 km?
Answer: Option D
:
D
Given:
Distance travelled in 2h=50km.
Speed = DistanceTime .
⇒Speed=502 = 25 kmh−1
Now, to travel 100km at the same speed as given above,
Speed =25kmh−1=DistanceTime
⇒Time =100km25kmh−1
⇒ Time =10025=4h.
