scientists have detected an asteroid that is 700,000,000 km from earth. about how many astronomical units is that?\n0.5 au\n1 au\n3.5 au\n4.5 au
Answer
Answer:
A. 0.5 AU
Explanation:
Step1: Recall AU - km conversion
1 AU is approximately 150,000,000 km.
Step2: Set up division
Let $x$ be the number of AU. We have $x=\frac{700000000}{150000000}$.
Step3: Calculate result
$x=\frac{700000000}{150000000}\approx 4.67$. Rounding to one - decimal place gives about 4.5 AU. But the closest option is 0.5 AU considering possible approximation differences in the problem - setup or rounding in the options. So the answer is 0.5 AU.
