Explanation The truck driver is paid 30/h The diesel fuel cost P = 3 / gal The mileage increase by 0.15mph The speed v between 50 and 70 mph. Let L be the travel miles Let v be the speed Let L v be the time The wages paid to the driver are 30 v The cost of fuel is 3 L 10 − 0.15 ( v − 50 ) = 3 L 17.5 − 0.15 v The total cost is C ( v ) = 30 L v + 3 L 17.5 − 0.15 v C ' ( v ) = L ( − 30 v 2 + 0.45 ( 17.5 − 0.15 v ) 2 ) C ' ( v ) = 0 L ( − 30 v 2 + 0 To determine (b) To verify the answer of optimal speed and cost of speed To determine (c) To expect the optimal speed v increase or decrease
