To convert kilometers to astronomical units (AU), you can use the conversion factor where 1 AU is approximately equal to 149.6 million kilometers (or 149,600,000 km).
To find out how many AU are in 700,000,000 km, you can divide the distance in kilometers by the number of kilometers in one AU:
\[
\text{Distance in AU} = \frac{700,000,000 \text{ km}}{149,600,000 \text{ km/AU}} \approx 4.68 \text{ AU}
\]
So, 700,000,000 km is approximately 4.68 AU. The closest answer option provided is **4.5 AU**.
