A car covers a distance in 40 minutes with an average speed of 60 km/h. What should be the average speed to cover the same distance in 25 minutes?
Explanation
A car covers a distance in 40 min with an average speed
=60 km/h= 60
60×1000 m/min
In 1 min the same distance can be cover with speed = 60
60×1000×40 =4000 m/min
In 25 min, the same distance can be cover with speed =
25
4000
=1600 m/min=1000
1600
×60=16×6=96 km/hr
