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:
hours, it must travel at a speed of: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 = |

1 2/3 is a mixed-fraction so 1st we have to multiply denominator with which is in-front of fraction & add it to numerator then we will get a 5/3.

240 Km/hr in 5 hours
5X60=300min
in 1 2/3 hrs to travel the same distance
1 2/3X60=100
=240/100X300=720
5X60=300min
in 1 2/3 hrs to travel the same distance
1 2/3X60=100
=240/100X300=720

Here the speed is given in Km/hr and time in hours, why the hours are not converted into mins ?

Those who says the answer is 720kmph please concentrate on my statement----.
If the answer is 720kmph then it means if we multi 720kmph with the given time of 1hr then we get the this which is 1200km isn't.
But did we get it?!
If the answer is 720kmph then it means if we multi 720kmph with the given time of 1hr then we get the this which is 1200km isn't.

Those who says answer as 720, why you are taken time as 5/3 hr instead of 1 hr as given in d example.
