Question 1087707: You have a 25-mile commute into work. Since you leave very early, the trip going to work is easier than the trip home. You can travel to work in the same time that it takes for you to make it 20 miles on the trip back home.

You can put this solution on YOUR website! Speed to work 25/t
Speed back from work 20/t
(25/t)-2 = 20/t
25-2t = 20
-2t = -5
t = 2.5
---------------------
to work: 25*2.5 = 62.5
back: 20*2.5 = 50

Although this seems EXTREMELY slow, .
Then again, besides a motor vehicle, the mode of transportation could be a bicycle/unicycle/skateboard, or other slower modes.
