A man takes 5 hours to walk to a certain place and returns by car. He would have, however, gained 3 hours if he had completed his entire journey by car. How long would he have taken to walk both ways?
5 hours
6.5 hours
7 hours
8 hour
6 hours
Walk + Car = 5 hours
Car + Car = 2 hours
Car = 1
Walk = 5-1 => 4 hours
Time taken to go and return by walking = 4 x 2 => 8 hours
