scientists have detected an asteroid that is 700,000,000 km from earth. about how many astronomical units is that? 0.5 au 1 au 3.5 au 4.5 au

Answer

Explanation:

Step1: Recall the conversion factor

1 astronomical unit (AU) is approximately 150,000,000 km.

Step2: Calculate the number of AU

Let $n$ be the number of AU. We use the formula $n=\frac{d}{150000000}$, where $d = 700000000$ km. So $n=\frac{700000000}{150000000}=\frac{14}{3}\approx4.67$. The closest value to 4.67 among the options is 4.5 AU.

Answer:

4.5 AU
