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
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 * 3/5) km/hr= 720 km/hr.
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 * 3/5) km/hr= 720 km/hr.
