Example 2:

Jan wants to measure the approximate distance from where she lives to the grocery store on the other side of town.

  • What is the most appropriate customary unit of measure she should use to measure the distance?
  1. inches
  2. feet
  3. yards
  4. miles
The answer to this problem would be D, miles. Using inches, feet, or yards may make her approximate distance more precise, but it isn't very feasible to measure the distance across town using a ruler or a yardstick. Larger distances are usually measured in miles.
