Question 548973: Two runners leave from the same location traveling in opposite directions. The first runner is running at 8 mph and the second is running at 10 mph. How long have they been running when they are 36 miles apart? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! They are running in opposite directions
so effective speed = 10+8 = 18 mph
d=36
time = 36/18 = 2 hours
