At 2:00 p.m. two cars start toward each other from towns 240 miles apart. If the rate of one car is 10 mph faster than the other, how fast does each car go if they meet at 5:00 p.m.? If 3x represents the distance that the slower car traveled, then which expression represents the distance the faster car traveled?
One car's rate is "r" and the other's is (r+10) the distance they cover is 240 miles in 3 hours 3r + 3*(r+10) = 240 6r + 30 = 240 6r = 210 r = 35 mph and the faster car is r + 10 = 45 mph
