A slow freight train chugs along a straight track. The distance it has traveled after x hours is given by a function f(x). An engineer is walking along the top of the box cars at the rate of 3 mi/hr in the same direction as the train is moving. Write a formula for the speed of the engineer relative to the ground in terms of x and f.
