The gas mileage m (x) (in mpg) for a certain vehicle can be approximated by m (x) = -0.031x+2.682x-35.015, where x is the speed of the vehicle in mph. Part: 0 / 2 Part 1 of 2 (a) Determine the speed at which the car gets its maximum mileage. Round your answer to the nearest mph. The gas mileage is at a maximum when the car travels at mph.
