I’m currently sitting in London, spinning at 640 miles per hour. My friend Sofía lives in Quito, Ecuador, and because of the equatorial speed bonus, she’s currently spinning much faster than me – at 1,037 mph. The Earth rotates once every 24 hours (roughly), and we all rotate with it. The circumference at the equator is about 24,901 miles, so at the equator, you’re spinning at about 1,037
