Question 1010138: Morgan and Autumn start out 58.8 miles apart. They begin riding their bicycles toward each other with Morgan riding four mph faster than Autumn. If they meet in three hours, how fast was each person riding? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call Autumn's rate, r. Then Morgan's rate is r+4.
Now rate times time equals distance, so we have
3r + 3(r+4) = 58.8 miles
3r + 3r + 12 = 58.8
6r + 12 = 58.8
6r = 46.8
r = 7.8 mph
r+4 = 11.8 mph
