Earth rotates on an axis through its poles. The distance from the axis to a location on Earth 30º north latitude is about 3429.5 miles. Therefore, a location on Earth at 30º north latitude is spinning on a circle of radius 3429.5 miles. Compute the linear speed on the surface of Earth at 40º north latitude.
