6-39.

The Earth travels $584$ million miles in the one year it takes to go around the sun. If there are $365$ days in a year, what speed does the Earth travel at in miles per day? What speed does the Earth travel at in miles per hour?

Review the Math Notes box in section 2.3.1

$\frac{\text{584 million miles}}{\text{1 year}}\cdot \frac{\text{1 year}}{\text{365 days}}=\frac{\text{1.6 million miles}}{\text{1 day}}$

Now calculate the speed of the Earth in miles per hour.
