Answer 1

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:

**StartFraction 1 mile Over 1.61 kilometers EndFraction**.
