You can put this solution on YOUR website! Wilbur left the hardware store and traveled toward the recycling plant at an average speed of 33km/h. Mary left two hours later and traveled in the same direction but with an average speed of 55km/h. How long did Wilbur travel before Mary caught up?
-----
Wilbur DATA:
rate = 33 km/h ; time = t hrs ; distance = 33t km
--------------
Mary DATA:
rate = 55 km/h ; time = t-2 hrs ; distance 55(t-2) km
------
Equation:
distance = distance
33t = 55(t-2)
33t = 55t-110
22t = 110
t = 5 hrs (time for Mary to catch up to Wilbur)
