Detailed explanation-2: -Earth revolves in orbit around the sun in 365 days, 6 hours, 9 minutes with reference to the stars, at a speed ranging from 29.29 to 30.29 km/s.

Detailed explanation-3: -So in one year, Earth travels about 584 million miles (940 million km). Since speed is equal to the distance traveled over the time taken, Earth’s speed is calculated by dividing 584 million miles (940 million km) by 365.25 days and dividing that result by 24 hours to get miles per hour or km per hour.

Detailed explanation-4: -It takes earth approximately 365.25 days to complete one revolution around the earth. Thus earth takes one year to complete one revolution around the sun. One day is approximately 23 hours and 56 minutes and thus it takes 365 times one day to complete a revolution.
