Question

what is mean velocity of the speed of earth ???​

Answer 1

about 67 thousand miles per hour

This means that in 365.25 days the Earth travels 587.5 million miles. This works out to about 67 thousand miles per hour. This is the speed we travel 24 hours a day, 365.25 days a year. The orbital velocity is 2πR/T where R is the average radius of the orbit and T is the length of the year.
