This problem can be solved with a very simple unit conversion.

Uh…no. An even simpler unit conversion.

We’ll start with the 7 and 5/6 inches on the map we’re given.

It’s much easier to solve this thing if we’ve got it in improper fraction form,

so we’ll change it up.

7 is the same as 42/6… and 42/6 plus 5/6 equals 47/6. Done.

Now, we can convert.

When we convert between units, all we’re doing is multiplying by a fancy form of 1.

We multiply 47/6 inches by 12 miles per 1/3 inch.

And we have, 12 divided by 1/3 is really just 12 times 3, so we have 47/6 times 36.

We can divide the top and bottom by 6 to get 47 times 6, which is equal to 282.

Our answer is (D).
