A bicyclist is riding on a path modeled by the function f(x) = 0.03x, where x and f(x) are measured in miles. Find the rate of change of elevation when x = 3.

  • calculus -

    Rate of change of elevation with horizontal distance or with time?

    For the latter, you need to know the speed.

    For the former, f' = df/dx = 0.03 at all times.
