Final answer:
The best unit of measurement for the distance between a school and a house is usually kilometers, as it is appropriate for longer distances commonly found between such locations.
Step-by-step explanation:
When considering the best unit of measurement for the distance between Mr. Rutledge's school and his house, we must take into account the typical length of such a distance. While units like centimeters and inches are good for small objects and yards might be used for measuring outdoor distances in some cases, they are not ideal for measuring the distance between two locations that are likely far apart. Instead, the best choice for this situation is most likely to be in kilometers, which are suitable for longer distances and commonly used for road measurements.
