Here's why it's not about miles:
* Rotation, not travel: Earth's rotation is about spinning on its axis, like a top. It's not traveling a distance in a straight line.
* Circumference matters: To understand the distance covered, we need to think about Earth's circumference. The Earth's circumference at the equator is roughly 24,901 miles.
So, while Earth doesn't "spin" miles, it does rotate 360 degrees in approximately 24 hours, covering the entire circumference of the Earth.
