Geography & Planet Earth
How fast, in km/h, does a point on Earth's equator move because of the planet's rotation (1 km/h ≈ 0.62 mph)?
Answer
1,670 km/h
That's nearly twice the cruising speed of a passenger jet — you're on the ride right now, but you can't feel it because the speed never changes. Rocket launch sites are placed near the equator to steal this free boost.
