So he "sauntered to shool" while going at twice that pace back home?. Using "x" as his pace while "sauntering" , he took 24/x hours to get to school and 24/(2x)= 12/x hour to go back home. Solve 24/x+ 12/x= 9 to find x.

How fast did he travel in each direction, and what were the two times?

(I don't simply want the answer. I want to know how to do it.)

Thank you
