Question

I need to know what city is located on 45 degrees N latitude but it has to be one of these cities Nashville Minneapolis Miami Boston Detroit Oakland Seattle Indianapolis Atlanta Jacksonville Pittsburg Cinncinnati Philidelphia Phoenix Charlotte

Please look at this map. Note that 45 degrees North is halfway between the 40- and 50-degree lines. The only city shown on this map that is at 45 North is St. Paul -- and that's not shown on this map. However, if you look at a map of Minnesota, you'll see that one of your cities is next to St. Paul, on the other side of the Mississippi River.
