The distance (in feet) of an object som a point is given by s(t) = r, where timer is in seconds. (a) What is the average velocity of the object between t = 3 and t = 5? The average velocity between t = 3 and 1 = 5 is i ft/sec. (b) By using smaller and smaller intervals around 3, estimate the instantaneous velocity at time = 3. Round your answer to the nearest integer. The instantaneous velocity at = 3 is about i ft/sec.
