Question 469562: A long distance trucker traveled 160 miles in one direction during a snow storm. The return trip in rainy weather was accomplished at double speed and took 4 hours less time. Find the speed going. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 160/x=160/2x+4
320=160+8x
160=8x
x=20
The trucker went 20 mph on the way there. He went 40 mph on the way back.
