In order to answer that question, we need to know the scale of the map.
Without that information, no answer is possible.
I think you have it in the first part of the question ... the part you decided
not to post.

OK. Now that you've provided the scale of the map,
answering the question is a piece-o-cake.
Use a proportion:
(1 inch on the map) / (4 miles on the ground) = ('x' on the map) / (17 miles on the ground)
One yard is 0.0005 miles,
548 * 0.0005 = 0.274,
So the answer is 0.274 miles.
Hope this helps.
9a^2 -6ab+ 12ac -8bc
This expression cannot be factorized because its terms don't have at least a common factor~
