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 Reply
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
