A passenger train leaves the train station 5 hours after a freight train left the same station. The freight train is traveling 3 0 mph slower than the passenger train. Which equation helps to find the rate of each train, if the passenger train overtakes the freight train in three hours. 3r = 5(r - 30)
3r = 8(r - 30)
3r = 8(r + 30)
5r = 3(r - 30)
