To convert meters to kilometers, you can divide the number of meters by 1,000.
Given:
\[ 3.875 \times 10^9 \text{ meters} \]
Now, convert to kilometers:
\[ \frac{3.875 \times 10^9 \text{ meters}}{1000} = 3.875 \times 10^6 \text{ kilometers} \]
So, \( 3.875 \times 10^9 \) meters is equal to \( 3.875 \times 10^6 \) kilometers.
