(TRANSPORTATION COST) A truck is hired to transport goods from a factory to a warehouse. The driver’s wages are figured by the hour and so are inversely proportional to the speed at which the truck is driven. The cost of gasoline is directly proportional to the speed. Express the total cost of operating the truck as a function of the speed at which it is driven.

  • math -

    wages = k/v
    gas = c v

    total = k/v + c v
