Question

How do I do this I forgot

Answer 1

So Salem and Yorshire are 4 inches apart on a map.

Scale: 1 inch : 7 miles

So 1 inch in the map is 7 miles.

4 * 7 = 28.

Your Answer:
They are 28 miles apart.

Answer 2

If on the map they are 4 in apart, all you have to do is substitute it in the scale which is 1 in : 7 mi, so 1 in would turn to 4 by multiplying it by 4, so you have to multiply 7 mi by 4 as well, so it would be 4 in : 28 mi, so it would be 28 mi apart.
