To convert kilometers to miles using the given ratio, we can set up a proportion based on the ratio of kilometers to miles.

The ratio states that:
\[
\text{kilometers} : \text{miles} = 1 : 0.6
\]

This means that for every 1 kilometer, there are 0.6 miles. To find how many miles correspond to 80 kilometers, we set up the equation:
\[
\text{miles} = \text{kilometers} \times 0.6
\]
Substituting 80 kilometers into the equation:
\[
\text{miles} = 80 \times 0.6 = 48 \text{ miles}
\]

Thus, Jeannie and her family need to drive **48 miles** to get to Moncton.
