98. 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:

✅ The correct answer is option D.
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.
