A standard Ford F150 has a standard tire size of 25.7 inches in diameter. You decided to replace the standard tires with a tire with a diameter of 28.2 inches without updating the onboard computer. Last week you were stopped for speeding on the highway where the speed limit is 65 mph. With the change in tires, how fast was the truck actually traveling when the speedometer read 65 mph? If you had used 24 inch tires, what would the actual speed have been if the speedometer read 65 mph?
