Suppose that the cost for a truck driver is $16.00 per hour and that the cost to operate the truck is v²/50000 per mile where v is the average speed of the truck. How fast should you recommend your driver to drive in order to minimize the total costs?

Hint: Convert the problem to Total Cost per Mile for Truck Driver and the Truck

The Cost per Mile for the Truck Driver will be $16.00 per hour divided by the number of miles driven in an hour which in this case would be v

The Cost per Mile for the Truck itself is given as v²/50000
