\bf \begin{array}{ccll}
hours&miles\\
\cline{1-2}
4&232\\
5.5&319
\end{array}~\hspace{10em}
(\stackrel{x_1}{4}~,~\stackrel{y_1}{232})\qquad
(\stackrel{x_2}{5.5}~,~\stackrel{y_2}{319})
\\\\\\
slope =
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{319-232}{5.5-4}\implies \cfrac{87}{1.5}\implies 58\frac{mi}{hrs}\impliedby \textit{rate of change}
