Question 1052777: Two buses leave Chicago at the same time in opposite directions. One travels at an average speed of 56mph and the other at 70 mph. In how many hours will they be 378 miles apart? Let x= time of the first bus and you = time of travel for the second bus. Solve the system by using method of addition. Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! If they leave in opposite directions at the same time, then their distance from each other increases at the rate of 56+70, or 126 mph. 378/126=3 hours before they are 378 miles apart. ☺☺☺☺
