The Earth's radius at the equator is about 6380km and rotates at 360 degrees every 24 hours. The angle of degrees is one degree per person on the equator for an hour

Answer 1

I do not understand your question. Please check the wording. ( I teach celestial navigation. )
Perhaps you are asking how many kilometers in a degree around the equator?
that would be 2 pi R/360 = 2 pi (6380/360) = 111 km approx
That is about 60 nautical miles,
which is just the way Napoleon wanted it when he defined a nautical mile as a minute of arc (1/60 degree) around the earth.
