Question 42

A farmer travelled a distance of 61 km. in a 9 hours. He travelled partly on foot at the rate of 4 km. per hour and partly on bicycle at the rate of 9 km. per hour. The distance travelled on foot is:

Solution

If t is the time travelled on foot, then 9-t is the time taken on the bicycle.

The distance travelled on foot + the distance travelled on bicycle=total distance travelled

thus, 4t + (9-t)9=61 , distance travelled=Speed x time

On solving we get t=4

So the distance travelled on foot=4x4=16 km
