The Position of a Car Is Given by the Values

The position of a car is given by the values in the following table.
$\begin{array}{|c|c|c|c|c|c|}\hline t \text { (seconds) } & 0 & 1 & 2 & 3 & 4 \\\hline s \text { (meters) } & 0 & 21.9 & 25.8 & 69.2 & 92.2 \\\hline\end{array}$

Find the average velocity for the time period beginning when $t = 2$ and lasting 2 seconds.

A) $46.1 \mathrm { ft } / \mathrm { s }$
B) $31.9 \mathrm { ft } / \mathrm { s }$
C) $33.5 \mathrm { ft } / \mathrm { s }$
D) $33.8 \mathrm { ft } / \mathrm { s }$
E) $\quad 33.2 \mathrm { ft } / \mathrm { s }$
