m= miles s=speed (MPH) m/s=miles 240/45=5.333 hours

Hours * minutes in an hour 5.33 * 60= 319.8

The answer is 320 minutes.

v=(d)/(t)\\\\v-velocity;\ d-distance;\ t-time\\-------------------------\\v=(d)/(t)\ \ \ \ |multiply\ both\ sides\ by\ t\\vt=d\ \ \ \ |divide\ both\ sides\ by\ v\\\\t=(d)/(v)\\------------------------


v=45\ mph;\ d=240\ mi\\\\t=(240)/(45)=(240:15)/(45:15)=(16)/(3)\ (h)\\\\1h=60min\\\\therefore\\\\t=(16)/(3)\cdot60min=16\cdot20min=\boxed{320min}
