Two cars leave town 150 kilometres apart at the same time and travel toward each other. One car's rate is 18 kilometres per hour more than the others. If they meet in 3 hours, what is the rate of the faster car ?

Answer 1

V1 = X km/h, V2 = x + 18 km/h.
d1 + d2 = 150 km.
3x + 3(x+18) = 150, 6x + 54 = 150, 6x = 96, X = 16 km/h, x+18 = 16 + 18 = 34 km/h = V2 = Speed of the faster car.
