Question 137109: John drove to a distant city in 5 hours, when he returned, there was less traffic, and the trip took only 3hrs. If John drove 26 mph faster on the return trip, how fast did he drive each way? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! 5X=3(X+26)
5X=3X+78
5X-3X=78
2X=78
X=78/2
X=39 MPH FOR THE FIRST TRIP
39+26=65 MPH FOR THE RETURN TRIP
PROOF:
5*39=3*65
195=195 MILEAGE DRIVEN.
