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
