per the comments, a table structure was asked for to make the question more clear
I added the table structure.
In this question I have 5 variables. I know three, and I am trying to understand what the relation one has to the other 2. Given I know :minlat, :minlong, and :distance, what I am trying to figure out is how they affect :maxlat and :maxlong.
How is this not a real question?
