Your brother starts out 10 minutes before you on a bike path and rides at a rate of 9 miles per hour. If you ride at a rate of 12 miles per hour, how long will it take you to catch up with him? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Your brother starts out 10 minutes before you on a bike path and rides at a rate of 9 miles per hour. If you ride at a rate of 12 miles per hour, how long will it take you to catch up with him?

Brother DATA:
rate = 9 mph ; time = x+(1/6) hrs ; distance = rt = 9x+(3/2) miles
-------------------------
Your DATA:
rate = 12 mph ; time = x hrs ; distance = 12x miles
-----------------------------
Equation:
distance = distance
9x + (3/2) = 12x
3x = 3/2
x = 1/2 hour (time to catch your brother)
