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

00:29

Uh…no. An even simpler unit conversion.

00:32

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

00:35

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

00:40

so we’ll change it up.

00:41

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

00:51

Now, we can convert.

00:53

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

00:57

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

01:05

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

01:14

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