Use the table below to estimate the velocity at \(\displaystyle t=5\) by averaging the slopes of the two adjacent secant lines corresponding to the two points closest to \(\displaystyle (5,13)\)
Using the point to the left gives \(\displaystyle m_1 = \frac{13-3}{5-0} = 2\). Using the point to the right gives \(\displaystyle m_2 = \frac{13-22}{5-10} = \frac{9}{5}\). Taking the average of the slopes gives \(\displaystyle \frac{2+\frac{9}{5}}{2} = \frac{19}{10}\). The estimate of the velocity is \(\displaystyle \frac{19}{10}\) meters per second.
\begin{question}Use the table below to estimate the velocity at $t=5$ by averaging the slopes of the two adjacent secant lines corresponding to the two points closest to $(5,13)$\newline
\begin{tabular}{|c|c|c|c|c|c|}\hline
$t$ seconds & 0 & 5 & 10 & 15 & 20 \\ \hline
$x$ meters & 3 & 13 & 22 & 28 & 38 \\ \hline
\end{tabular}\newline
\soln{9cm}{Using the point to the left gives $m_1 = \frac{13-3}{5-0} = 2$. Using the point to the right gives $m_2 = \frac{13-22}{5-10} = \frac{9}{5}$. Taking the average of the slopes gives $\frac{2+\frac{9}{5}}{2} = \frac{19}{10}$. The estimate of the velocity is $\frac{19}{10}$ meters per second.}
