Two trucks leave a warehouse at the same time. One travels due south at an average speed of 48 miles per hour, and the other travels due north at an average speed of 47 miles per hour. After how many hours will the two trucks be 427.5 miles apart?

59x + 62x   = 605      x = number oh hours travelled by each truck

x = 5 hours
