ANSWER:
3 hours
STEP-BY-STEP EXPLANATION:
We have that the speed is given as follows:
[tex]\begin{gathered} v=\frac{d}{t} \\ \text{where, } \\ v=\text{ speed = 2.75 mi/hr} \\ d\text{ = distance = 8.25 mi} \\ t\text{ = time } \end{gathered}[/tex]To calculate the time it would take, we must replace in and solve for t, like this:
[tex]\begin{gathered} 2.75=\frac{8.25}{t} \\ t=\frac{8.25}{2.75} \\ t=3\text{ hr} \end{gathered}[/tex]Which means it would take you 3 hours
