Intermediate Algebra (6th Edition)

We are given that Earth is 92.9 million miles from the sun. We are also told that AU is the average distance between Earth and the sun, or 92.9 million miles. Therefore, we can divide Earth's distance from the sun by 92.9 million miles in order to calculate Earth's AU from the sun. $\frac{92.9}{92.9}=1$ AU from the sun. This result makes sense, given that AU is measured by the distance between the Earth and the sun.
