Two buses leave towns 1270 kilometers apart at the same time and travel toward each other. One bus travels 20 km/h faster than the other. If they meet in 18 hours, what is the rate of each bus?
Bus 1 speed = x
Bus 2 speed = x + 20
Rate * time = distance
(x + x+20) * ( 18 ) = 1270 km solve for 'x' the slower bus, the other bus is x + 20 km/hr
