Chapter 2.1, Problem 16E

To determine

To complete: The following table with the appropriate average velocities of the object moving with the position function $s\left(t\right)=-4.9t^2+30t+20$ and then make the conjecture about the value of the instantaneous velocity at $t=2$.

Time Interval	$\left[2,3\right]$	$\left[2,2.5\right]$	$\left[2,2.1\right]$	$\left[2,2.01\right]$	$\left[2,2.001\right]$
