Question 43324: Two boys on bikes start at the same time at the same place and travel opposite directions. One travels at the rate of 10 miles per hour and the other at the rate of 6 miles per hour. In how many hours will they be 72 miles apart? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The boys are getting further apart at a combined rate
of their two speeds.
combined rate = 10 + 6 = 16 mi/hr
d / r = t
d = 72 miles
72 / 16 = t
t = 4.5 hrs answer
