Question

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

Answer 1

`\begin{gathered} \text{The fuction is }(1)/(3)d\text{ = t while the coordinates of points on the graph is represented by (d, t)} \\ \\ \text{When d = 7}(1)/(2), \\ (1)/(3)\text{ (7}(1)/(2))\text{ = t} \\ \\ =\text{ }(1)/(3)\text{ x }(15)/(2) \\ =(5)/(2)\text{ =}2(1)/(2)\text{hrs} \\ \\ \text{The point that represents the time it took to walk 7}(1)/(2)miles\text{ is (7}(1)/(2),\text{ 2}(1)/(2)) \end{gathered}`
