Answer:

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:

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

This can now be simplified:
↓ multiplying by
(which is 1, so we aren't changing the value)

↓ dividing by
(which is also 1)

↓ rewriting as a mixed number

↓ converting the third of an hour to minutes
