# The Time Taken by the Plane to Cover 9000 km is :

A plane can cover 6000 km in 8 hours. If the speed is increased by 250 kmph, then the time taken by the plane to cover 9000 km is

- 5 hours
- 8 hours
- 6 hours
- 9 hours

**Answer: (4) 9 hours**

**Explanation:-
**A plane can cover 600 km = 8 hours

Then, the Speed of a plane = 6000/8 (Speed = distance/time)

= 750 km/hr

If the speed increased by 250 km/hr

Then, the speed of a plane = 750 + 250 = 1000 km/hr

Time taken by plane to cover 9000 km = 9000/1000

= 9 hrs

Then, the time taken by plane to cover 9000 km is 9 hrs.

Hence, the answer is (4) 9 hrs.
