Hello!
This is an exercise about interpretation.
We usually use miles to express very large distances. For example, on highways, there are signs indicating the distance in miles to cities.
Inches are used to calculate small distances. One example of this is that we can use a ruler to measure in inches.
And to finish, meters are bigger than inches and smaller than miles. So, it's better to use meters to measure the distance of city blocks.
• inches < ,meters ,< miles
