Answer:
The distance is 55.636 billion miles, or 528.2 AU.
Explanation:
Since the distance from the Sun to Neptune is 2.7818 billion miles, the distance from the Sun to Planet Nine would be 20 times that, which is:
![d=(20)(2781800000\ miles)=55636000000\ miles](https://tex.z-dn.net/?f=d%3D%2820%29%282781800000%5C%20miles%29%3D55636000000%5C%20miles)
or 55.636 billion miles.
Since 1 astronomical unit (AU) is 93 million miles, that distance is also:
![d=(55636000000\ miles)(\frac{1AU}{93000000\ miles})=598.2\ AU](https://tex.z-dn.net/?f=d%3D%2855636000000%5C%20miles%29%28%5Cfrac%7B1AU%7D%7B93000000%5C%20miles%7D%29%3D598.2%5C%20AU)
