Calculate the instantaneous velocity for the indicated value of time (in s) of an object for which the displacement (in ft) is given by the indicated function. Calculate values of the average velocity for the given values of t and note the apparent limit as the time interval approaches zero.

s=4t+5; when t=4; use values of t of 3.0, 3.5, 3.9, 3.99, and 3.999
