Verified Answer :

To convert 48.25 kilometers to miles using the conversion factor \(\(1.61 \, \text{kilometers} = 1 \, \text{mile}\)\), we can follow these steps:

1. Identify the conversion factor:
- We know that \(\(1 \, \text{mile} = 1.61 \, \text{kilometers}\)\).

2. Set up the conversion:
- To convert kilometers to miles, we need to divide the number of kilometers by the number of kilometers in one mile. This can be formulated as:
\(\[ \text{miles} = \frac{\text{kilometers}}{1.61} \]\)

3. Apply the given value:
- We have \(\(48.25 \, \text{kilometers}\)\). Plugging this value into our formula, we get:
\(\[ \text{miles} = \frac{48.25 \, \text{kilometers}}{1.61} \]\)

4. Execute the division:
- When we divide \(\(48.25\)\) by \(\(1.61\)\), we get:
\(\[ \text{miles} \approx 29.96894409937888 \]\)

So, the conversion of 48.25 kilometers to miles yields approximately \(\(29.96894409937888\)\) miles.

Therefore, the closest correct answer from the provided options is:
29.9 miles.
