An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1 hours, it must travel at a speed of:
300 kmph
360 kmph
600 kmph
720 kmph
Answer: Option
Explanation:

Distance = (240 x 5) = 1200 km.

Speed = Distance/Time

Speed = 1200/(5/3) km/hr.     [We can write 1 hours as 5/3 hours]

Required speed = 1200 x 3 km/hr = 720 km/hr.

Distance= S * T.
Given 240km/hr in 5hr.
So,1hr =240 km.
then 5hr ---> 5*240 = 1200 km.

Now to cover distance 1200km in 5/3hr.
So, you can apply speed formula and the answer will 720 km/hr.
