The Goodyear Tire Company is testing a new tire. The tires are placed on a machine that can simulate the tires riding on a road. The machine is first set to 60 mph and the tires run at the speed for 7.2 hours. The machine is then set to a second speed and run at this speed for 6.8 hours. After this 14-hour period,the machineindicated the tires have traveled the equivalent of 908 miles. Find the second speed to which the machine was set.

How do you determine how to set it up? I'm confused.
