The car leaving W travels 10 miles per hour more than the other and they meet after 1 hour and 36 minutes. What is the average speed of the car? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! D=RT
192=(X+X+10)1.6
192=(2X+10)1.6
182=3.2X+16
3.2X=192-16
3.2X=176
X=176/3.2
X=55 MPH FOR THE SLOWER CAR.
55+10=65 MPH FOR THE FASTER CAR.
PROOF:
192=(55+65)1.6
192=120*1.6
192=192
