An airplane covers a distance at a 240 km/hr in 7 hours. To cover the same distance in 8/3 hours, it must travel at what speed?

Answers 2

Explanation:

Aeroplane covers a certain distance at a speed of 240 km/h in 5 hours

Time taken, t = 7

Speed, v= 240

Distance covered, d = tv = 7*(240) = 1680

Let t1 and v1 be the required speed and time respectively.

t1 = 8/3

v1 = 1680/(8/3) = 630

Ans: To cover the same distance in 8/3 hours, required speed = 630km/h

Answer:

630 km/hr

Explanation:

total distance=240×7=1680

new time=8/3 hrs.

speed=1680/8/3

=1680×3/8

=5040/8

=630
