An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in $1 \frac{2}{3}$ hours, it must travel at a speed of:

A. 300 kmph

B. 360 kmph

C. 600 kmph

D. 720 kmph

Correct Answer :

D. 720 kmph

Distance = (240 x 5) = 1200 km.
Speed = Distance/Time
Speed = 1200/(5/3) km/hr. [We can write

1 \frac{2}{3}

hours as 5/3 hours]

∴ R e q u i r e d s p e e d = (1200 x \frac{3}{5}) k m / h r = 720 k m / h r .
