    Practical Max/min

    The cost of running a car at an average speed of v km/h is given by c=150+\frac{v^2}{80} cents per hour. Find the average speed, to the nearest km/h at which the cost of a 500km trip is a minimum. Answer: 110km/h. This may well be a 2U question. Hard to tell though since it's in a 2U/3U book.
