Question

This distance from the Earth to the Sun given above is a standard for measuring other distances in the solar system and is called an Astronomical Unit or AU. 1AU=_________miles. Write this as a ratio:_________

Answer 1

The Astronomical Unit (AU) is approximately
`92.96* 10^(6)\,mi`, the ratio of Astronomical Units per mile is
`r = 1\,AU\,:\,92.96* 10^(6)\,mi`.

Step-by-step explanation:

The distance from the Earth to the Sun is approximately
`92.96* 10^(6)\,mi`, then the Astronomical Unit (AU) is approximately
`92.96* 10^(6)\,mi`. The ratio can be described by the quantity of miles per Astronomical Unit, then we define:

`r = 1\,AU\,:\,92.96* 10^(6)\,mi`.
