To convert kilometers to miles, we can use the conversion factor: 1 kilometer is approximately equal to 0.621371 miles.
When we need to convert 32 kilometers into miles, we multiply the number of kilometers by the conversion factor:
\[ 32 \text{ km} \times 0.621371 \text{ miles/km} = 19.883872 \text{ miles} \]
Now, to express this answer to the nearest mile, we round the converted value to the nearest whole number. In this case, 19.883872 miles is closer to 20 miles than it is to 19 miles, so when rounded to the nearest mile,
\[ x = 20 \text{ miles} \]
Therefore, 32 kilometers is equal to 20 miles when rounded to the nearest mile.
