Which is closest to a true nautical mile at the equator:

1. A nm that runs north to south
or
2. A nm that runs east to west?

If they are both one nautical mile, then they are equal.

A better question might be which is closest to a nautical
mile at the equator. One minute of latitude or one minute
of longitude.
