Question 236396: Two cars start at point A. Car 1 travels from point A to point C. Car 2 travels from point A to B to C. The distance between point A and point B is 140 miles. The distance between point B and C is 200 miles. Car 2 drive at 60mph from point A to B and at 50mph from point B to C. If both cars arrive at the same time, how fast did car 1 drive. Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! D=RT OR T=D/R
140+120=260
T=140/60+120/50
T=2.333+2.4=4.733 HOURS FOR CAR 2.
4.733=260/R
4.733R=260
R=260/4.733
R=54.933 MPH WAS THE SPEED OF CAR 1.
