Question

a person covers a distance of 16 km in 2hour 20min partly on foot at the speed of 3km/h and on bicycle at the speed of 10km/h . find the distance covered on foot​

Answer 1

Answer:

Let the time he walks be x hours

From the given condition

3(x)+9(3−x)=15⟹6x=12⟹x=2

So the time he runs is 3−2=1 hour

Distance covered by running is 1×9=9 km
