A truck has a minimum speed of 14 mph in high gear. When traveling x mph, the truck burns diesel fuel at the rate of 1225 gal 0.0043315 + x mile Assuming that the truck can not be driven over 59 mph and that diesel fuel costs $1.96 a gallon, find the following. (a) The steady speed that will minimize the cost of the fuel for a 500 mile trip. (b) The steady speed that will minimize the total cost of a 500 mile trip if the driver is paid $13 an hour. = X (c) The steady speed that will minimize the total cost of a 390 mile trip if the driver is paid $23 an hour.
