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 :

Solution (By Examveda Team)

$$\eqalign{ & \text{Distance}=\left(240\times5\right) \text{ km} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \text{ = 1200 km} \cr & \therefore \text{ Required Speed:} \cr & = \frac{\text{Distance}}{\text{Time}} \cr & = \frac{1200}{\frac{5}{3}} \cr & = \left( {1200 \times \frac{3}{5}} \right){\text{ km/hr}} \cr & = 720{\text{ kmph}} \cr} $$
