Answer:


645\text{ hr } 20\text{ min} \ \ \text{ OR }\ \ 645 (1)/(3)\text{ hr}

Explanation:

To figure out how much time it will take to travel a set distance at a constant speed, we can multiply the distance by the speed ratio in a form so that the distance units will cancel:


6,\!776\text{ mi} \cdot \frac{1 \text{ hr}}{10.5 \text{ mi}}

We can see that the mile units cancel, and we are left with the total time that the traveling takes:


(6,\!776)/(10.5) \text{ hr}

This can now be simplified:

↓ multiplying by
(2)/(2) (which is 1, so we aren't changing the value)


(13,\!552)/(21)\text{ hr}

↓ dividing by
(7)/(7) (which is also 1)


(1936)/(3)\text{ hr}

↓ rewriting as a mixed number


645 (1)/(3)\text{ hr}

↓ converting the third of an hour to minutes


\boxed{645\text{ hr } 20\text{ min}}
