Question 947322: John drove to the park at 4o mph and returned walking at 4 mph. Find his walking time if it was 9 hours longer than his driving time. How far was it to the park? Answer by amarjeeth123(570) (Show Source):
You can put this solution on YOUR website! Let the distance be x miles.
Time taken for the drive=x/40
Time taken for the walk=x/4
x/4-x/40=9
(10x-x)/40=9
9x=40*9
x=40
The park was 40 miles away.
