During a walk a thin Noah’s time in hours, t, and distance in miles, d, are related by the equation 1/3d = t. A graph of the equation includes the point (12, 4) What point would represent the time it too to walk 7 1/2 miles
[tex]\begin{gathered} \text{The fuction is }\frac{1}{3}d\text{ = t while the coordinates of points on the graph is represented by (d, t)} \\ \\ \text{When d = 7}\frac{1}{2}, \\ \frac{1}{3}\text{ (7}\frac{1}{2})\text{ = t} \\ \\ =\text{ }\frac{1}{3}\text{ x }\frac{15}{2} \\ =\frac{5}{2}\text{ =}2\frac{1}{2}\text{hrs} \\ \\ \text{The point that represents the time it took to walk 7}\frac{1}{2}miles\text{ is (7}\frac{1}{2},\text{ 2}\frac{1}{2}) \end{gathered}[/tex]
