Avehicle can make a 100 mile trip using $30 worth of fuel if it travels at an average speed of 60 mph. the same vehicle uses $42 worth of fuel for the same trip if it travels at an average speed of 120 mph. the other non-fuel costs for the trip total $20 per hour.
a) find the fuel cost for the trip as a linear function of the average speed, v.
b) find the non-fuel cost for the trip. remember that time=distance/v.
c) find the average speed that minimizes the total cost of the trip.
