At the north pole one degree of longitude extends how many kilometers on the ground?

Also: A spot on the Earth's surface rotates fastest at the ____: Tropic of cancer? North pole? Arctic circle? Tropic of Capricorn? The Equator? Thank you to anyone that takes the time to answer these two simple questions.

1. 0 km. They all rotate at the same speed - 360 degrees per day.
2. 0 km The Equator What does this prove about you?
3. 0 km, there is no longitude at the north pole, it's a single point, 90° N latitude. The angular velocity is highest at the equator. A point covers more distance in the same amount of time. The rotational velocity is the same at all latitudes, 360° / day.
4. 0 kilometers Equator. The rotational speed of spot at the equator is 436m/s
