WebJan 7, 2024 · If we move halfway up the globe to 45 degrees in latitude (either north or south), the speed of earth's rotation can be calculated by using the cosine (a trigonometric function) of the latitude i.e, cos(45) = .707 and the speed is .707 x 1670 = 1180 kilometers/hr. This formula can be used to find the speed of rotation at any latitude.
