To find the conversion factor to convert kilometers to miles, we need to start with the information provided in the table.
According to the table: 1 mile = 1.61 kilometers
To convert kilometers to miles, we can rearrange this relationship.
We can express 1 kilometer in terms of miles using the conversion factor derived from the original statement:
1 kilometer = \( \frac{1}{1.61} \) miles.
This means the conversion factor to convert kilometers to miles is:
\[ \frac{1 \text{ mile}}{1.61 \text{ kilometers}} \]
Thus, the correct answer is:
