How fast is the world turning in chino hills?

The Earth rotates at a speed of approximately 1,670 kilometers per hour (about 1,040 miles per hour) at the equator. However, this speed decreases as you move toward the poles. In Chino Hills, California, which is located at around 34 degrees north latitude, the rotational speed is slightly less, roughly 1,300 kilometers per hour (about 800 miles per hour). This rotational speed remains relatively constant throughout the day.
