Question

a bus covered 7 1\2 km in one hour and a car covered 3 4\9 m more distance than bus in the same time . find the distance covered by the car

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
