[tex]1h=60min\\\\65\dfrac{mi}{h}=65\dfrac{mi}{60min}=\dfrac{65mi}{60min}=\dfrac{13}{12}\dfrac{mi}{min}\\\\\begin{array}{ccc}\dfrac{13}{12}mi&-&1min\\\\125mi&-&xmin\end{array}\ \ |cross\ multiply\\\\\dfrac{13}{12}x=1\cdot125\\\\\dfrac{13}{12}x=125\ \ \ |multiply\ both\ sides\ by\ \dfrac{12}{13}\\\\\boxed{x=\dfrac{1500}{13}\approx115.38\ (min)}[/tex]
Given speed (s) and distance (d), the time (t) needed to travel may be calculated through the formula,
                                 t = d / s
Plugging in the values to the equation with the conversion of hour to minutes,
        t = (125 miles) / ((65 miles/hr) x (1 hour / 60 minutes)) = 115.38 minutes
Therefore, it will take approximately 115.38 minutes to drive to San Diego.
