Gas mileage is tested for a car under different driving conditions. At lower speeds, the car is driven in stop-and-go traffic. At higher speeds, the car is overcoming more wind resistance. The variable x given in the table represents the speed (in mph) for a compact car, and m (x) represents the gas mileage (in mpg).

Round to the nearest ten-thousandth, hundredth, and tenth, respectively. The function is m (x) = X 5
