How long will the trip be if they dont stop?

We have the following relationship:
[tex]\begin{gathered} 65\text{ miles ----- 1hour} \\ 648\text{ miles ---- x} \end{gathered}[/tex]By applying the rule of three, we get
[tex]x=\frac{(648)(1)}{65}[/tex]then, x is given by
[tex]\begin{gathered} x=\frac{648}{65} \\ x=9.969 \end{gathered}[/tex]this means that the trip will take around 10 hours
