A newly discovered solar system is found 300 billion kilometers from the sun. How many AU does this represent? Show your work.
Aleksandr-060686 [28]

1 kilometer = 6.68 × 10^{-9} (<<<AU is in scientific notation here)

To convert 300 billion kilometer (3,000,000,000 km)  into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 × 10^{-9})

3,000,000,000 × (6.68 × 10^{-9}) =  20.04 AU

Hope this helped!
