Why the speed of rotation at Singapore is much faster than Tokyo?

The speed of rotation at Singapore is faster than that of Tokyo primarily due to their respective latitudes. Singapore is located near the equator, where the Earth's circumference is greatest, resulting in a higher linear speed of rotation. In contrast, Tokyo is situated further north, where the circumference decreases, leading to a slower linear speed. Therefore, as the Earth rotates, locations closer to the equator, like Singapore, experience a faster rotational speed compared to those further north, such as Tokyo.
