A Car Is Observed to Have the Following Velocities at Times

Short Answer

A car is observed to have the following velocities at times t = 0, 2, 4, 6:
$\begin{array}{ccccc}\text { time }(\mathrm{sec}) & 0 & 2 & 4 & 6 \\\text { velocity }(\mathrm{ft} / \mathrm{sec}) & 0 & 23 & 42 & 68\end{array}$ Give the lower estimate for the distance the car traveled.
