Two trucks leave a warehouse at the same time. One travels due south at an average speed of 58 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 787.5 miles apart?

Distance = Rate x Time in this case, D = 787.5 miles because each driver will drive for the same length of time, we can use their average rate so, D = average rate x Time 787.5 miles = (58mph + 47mph)/2 x Time 787.5 miles / 52.5 mph = 15 hours Since the total time is 15 hours, each driver will drive for 7.5 hours. Answer: Therefore, the total hours is 15 hours when the two trucks are 787.5 miles apart.
