Earth_speed_at_45_degrees_is_700_mph_ Classic Round Sticker

Earth_speed_at_45_degrees_is_700_mph___ because Earth speed at Equator is 1000 mph. On this diagram the Earth radius is 5 squares from centre to equator. We assume Earth is a sphere (although it is actually slightly a greater radius from centre at the equator). We measure the distance from 45 degree latitude Earth surface to Earth axis as 3.5 squares. 3.5 / 5 x 1000 = 7/10 x 1000 = 700 mph Earth speed at the 45 degree latitude using these figures. 45 degree latitude runs across the northern United States: Between Montana and Wyoming, across the northern edge of the Michigan 'mitten', across the northern edge of New York state and Vermont and through middle of Maine. People living south of this line are moving around the Earth faster than 700 mph even as they are asleep in their beds.
