Denver, Colorado and Madrid, Spain are at nearly the same latitude (about 40°N). If you travel from Denver to Madrid staying at the same latitude the entire trip, will you be taking the shortest route?
A) No. The shortest path on the Earth has to be a great circle. B) No. The shortest path on the Earth must always be a straight line. C) Yes. A flat map of Earth shows this path to be straight, and a path that is straight on a map is the shortest path. D) Yes. Staying at a constant latitude guarantees the shortest path.
