You can put this solution on YOUR website! A vintage car leaves Des Moines,Iowa traveling at the rate of 45 miles per hour.
One hour later a faster car sets out from the same town to overtake the first.
At what rate must the faster car travel in order to overtake the first in 5 hours?
-------------------
Faster Car DATA:
time = 5 hrs; rate = x mph ; distance = 5x miles
---------------
Vintage DATA:
rate = 45 mph ; time = 6 hrs: distance = rt = 6*45 = 270 miles
---------------
Equation:
distance = distance
5x = 270
x = 54 mph (rate of the faster car)
