The government requires speedometers on cars sold in the United States to be accurate within ±2.5% of
the actual speed of the car. If your speedometer reads 60 miles per hour while you are driving on a
highway, what is the range of possible actual speeds at which your car could be traveling?

60 - .025(60) = 58.5 m/hr

60 + .025(60) = 61.5                     range    58.5 - 61.5 m/hr
