* Earth's orbital speed: The Earth travels around the sun at approximately 67,000 miles per hour.

* Time in a day: There are 24 hours in a day.

Calculation:

* Distance traveled in a day = Speed x Time

* Distance traveled in a day = 67,000 miles/hour * 24 hours

* Distance traveled in a day = 1,608,000 miles

Therefore, the Earth travels approximately 1,608,000 miles around the sun in one day.
