Given :- A plane covers a distance of 6000 km in 8 hours. If his speed is increased by 250 km/h . How long will it take the plane to cover the distance of 900 km ?
Solution :-
from given data,
→ Distance covered by plane = 6000 km.
→ Time taken = 8 hours .
So,
→ Speed of plane = (Distance / Time) = 6000/8 = 750 km/h .
now,
→ Distance covered by plane = 9000 km.
→ New speed = 750 + 250 = 1000km/h.
therefore,
→ Time taken by plane = New distance / New speed = 9000 / 1000 = 9 hours. (Ans.)
Hence, Plane will take 9 hours to cover 9000 km at new speed.
