Is the earth spinning 1000mph?

So, the rotational velocity at the equator is ~1000mph.  Hard to beleive?  I guess so but if you consider the circumference of the earth has been measured at 24901 miles, and a day is 24 hours, it sure adds up.  It actually spins at 15 degrees per hour and if you multiply 15*24 you get 360 which describes a full rotation.  If you consider 1 degree is 69 miles and you multiply 69*360 you arrive at approximately the stated circumference.

Also, rotation is usually measured in RPM/RPH but since flat earthers make this a big deal, we'll work in MPH today.  Now you can tell a flerf how slow we are!

We are actually one of the slower rotating planets.  Here's a list of planets in our solar system along with their circumferential and rotational velocities at the equator in miles per hour (mph) and their classification. Please note that the rotational velocity can vary slightly depending on latitude.

Mercury
Circumferential Velocity: ~6,750 mph
Rotational Velocity: ~7 mph
Class: Terrestrial Planet
Venus
Circumferential Velocity: ~29,000 mph
Rotational Velocity: ~4 mph (retrograde)
Class: Terrestrial Planet
Earth
Circumferential Velocity: ~1,040 mph
Rotational Velocity: ~1,040 mph
Class: Terrestrial Planet
Mars
Circumferential Velocity: ~8700 mph
Rotational Velocity: ~866 mph
Class: Terrestrial Planet
Jupiter
Circumferential Velocity: ~29,200 mph
Rotational Velocity: ~28,000 mph
Class: Gas Giant
Saturn
Circumferential Velocity: ~21,700 mph
Rotational Velocity: ~21,500 mph
Class: Gas Giant
Uranus
Circumferential Velocity: ~9,600 mph
Rotational Velocity: ~9,000 mph
Class: Ice Giant
Neptune
Circumferential Velocity: ~9,600 mph
Rotational Velocity: ~9,000 mph
Class: Ice Giant
