Question

what is the speed of Earth revolution ​

Answer 1

Time to complete one Orbit = 365.2422 days = 8766 hr. Speed of Revolution = Distance/Time = 942,000,000 km / 8766 hr = 107,000 km/hr = 30 km/sec. In the typical time it takes to read this sentence (about 15 seconds), the Earth will have moved through space by about 450 km, or about the width of the state of Ohio.
