Final answer:
The Earth orbits the Sun at an average speed of approximately 110,000 kilometers per hour, equating to about 66,000 miles per hour once converted.
Step-by-step explanation:
The Earth travels approximately 110,000 kilometers per hour as it orbits the Sun. One complete orbit takes about one year, which is equivalent to 3 × 107 seconds. Converting this speed to miles, for those who prefer it, involves multiplying by 0.6, which gives us around 66,000 miles per hour. Despite the high speed of Earth's orbital motion, we do not feel it because of gravity binding us to the Earth's surface and the lack of resistance in the vacuum of space.
