Question

7. The earth revolves around the sun at a speed of about per second.​

Answer 1

Answer:

30 kilometers per second

Answer 2

Earth's average orbital speed is about 30 kilometers per second. In other units, that's about 19 miles per second, or 67,000 miles per hour, or 110,000 kilometers per hour (110 million meters per hour). We learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour. So, Earth travels around the sun at a speed of 1,09,927 kilometers per hour.
