EMERGENCY PLEASE HELP A gift shop uses a commercial minivan for deliveries. The fuel expenses are defined by the function C = 0.005 V^2, where V mph is the speed of the minivan and C = cost of fuel per hour. If the driver's rate is $20 per hour, find what speed the driver should use to minimize the cost of a 80 mile delivery for the gift shop. Consider only cost of fuel and wages. Find exact value and then round your answer to the nearest whole number. btw the answer is not 40√10
