Question 1045655: Two cars, which are 570 miles apart and whose speeds differ by 2 miles per hour, are moving toward each other. If they meet in 5 hours, find the speed of each car. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! D = rt
570 = 5(r+2) + 5r
570 = 5r + 10 + 5r
570 = 10r + 10
560 = 10r
56mph = r, slower car's speed
58mph , the speed of the faster car
CHECKING
5hr*58mph + 5hr*56mph = 290m + 280m = 570m CHECKS
