EVERYDAY SCIENCE

Detailed explanation-1: -At the equator, its circumference is roughly 40, 075 kilometres, so dividing this by the length of day means that, at the equator, Earth spins at about 1670 kilometres per hour.

Detailed explanation-2: -Complete answer: At its Equator, the Earth is the largest. The sidereal duration is 23 hours, 56 minutes, and 4.09053 seconds, and the earth’s diameter is approximately 40, 075 kilometers. At the equator, the earth’s crust travels at a rate of 460 meters per second, or around 1, 000 miles per hour.

Detailed explanation-3: -Circumference of the Earth at 40-deg North = 30, 600 kilometers. Time to complete one Rotation = 24 hours. Speed of Rotation at 40 North = Distance/Time = 30, 600 km / 24 hr = 1280 km/hr.

Detailed explanation-4: -The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40, 075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1, 000 miles per hour.

Detailed explanation-5: -If you estimate that a day is 24 hours long, you divide the circumference by the length of the day. This produces a speed at the equator of about 1, 037 mph (1, 670 km/h). You won’t be moving quite as fast at other latitudes, however.
