Do the math -  Equatorial circumference is 40,075 km therefore 1

True enough, with respect to the sun. Hold this thought.

The 'sidereal time' guys have the Earth rotate 1675 km for 15 degrees

This is not true, we don't do that, because our frame of reference
here is the fixed stars, and the 15 degrees there, more accurately
called 15 degrees of Right Ascension, takes less than an hour to
transverse, due to the Earth's own motion along its orbit. Relative to
the sun, 15 degrees on the surface of the Earth = 1 hour on our Earth-
time clock, no worries; relative to the stars, 15 degrees of Right
Ascension is a little less than an hour, and you can measure this
yourself, no need to take my word for it. Because of Earth's motion
along its orbit, 24 hours of Right Ascension is transversed in
23:56:04 on that same earth-time clock. Of course, it would be 24
hours on a sidereal clock. So what? The main point here is that there
is NO CONFLICT between solar and sidereal time, no matter how badly
this might hurt your argument. As always, FRAMES OF REFERENCE!!!!

or 40,200 km for 360 degrees

This not true, because we are NOT multiplying that 1675 km for 15
degrees by 24 hours, we are multiplying it by 23:56:04, so we get the
same circumference, 40,075. It is just not possible to fool Mother
Nature, and no one here is trying to do so.

so what you are going to do with the
excess 125 km geography at the Equator is anyone's guess.

Answered above, there is no disagreement here, we are all on the same
page. If you have to guess, well, you just don't understand all of the
facts as well as you should. Back to the textbooks for you.
