Question
an object is moving in a striaght line awy from a fixed point on that line. Its distance (in fee) from that point is given by s(t) = t^2, where time t is in seconds. Waht is the average velocity of the object between t =3 and t=5.6?

Hi, Jennifer,
         s(5.6) - s(3)
Avg vel = ---------------
           5.6 - 3

That's all there is to it.
