    If the speed varies by 3 mph while cruising, it means that the care can be 3 mph slower, or 3mph faster than it should be. To find the different in these min and max speeds, you have to substract them. If the car travels at min: x-3 mph max: x+3 mph then the difference is (x+3) - (x-3) = 6 or, if you want to keep it simple: 3 - (-3) = 6
