Question 1046163: Skyler and Roberto both leave the bookstore at the same time, but in opposite directions. If Roberto travels 7 mph faster than Skyler and after 5 hours they are 125 miles apart, how fast is each traveling? Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! Let s = Skyler's speed.
===> s+7 = Roberto's speed.
===> 5s + 5(s+7) = 125
===> 5s +5s +35 = 125 ===> 10s = 90 ===> s = 9 mph, Skyler's speed.
===> Roberto's speed is 16 mph.
