Step-by-step explanation:speed = distance / timeto get distance, we have to multiply by time. the speed the 2 busses are moving seat from each other isx + (x + 17) = 2x + 17x = the speed of one busx + 17 = the speed of the other bus. so, after 4 hours the distance between them is(2x + 17) × 4 = 8362x + 17 = 2092x = 192x = 96 km/hbus 1 travels at 96 km/h.bus 2 travels at 96+17 = 113 km/h.
