Final answer:
In sports, especially within the United States, certain events use customary units instead of SI units. Examples include the football field measured in yards, the mile run, and the high jump measured in feet and inches.
Step-by-step explanation:
The question involves identifying athletic events that do not use the SI unit of measurement. Here are three examples:
- The length of a football field in the United States is typically measured in yards, not meters.
- Two other examples where customary units are typically used instead of SI units are the mile run (distance measured in miles), and the height in high jump (often measured in feet and inches in the USA).
The SI base units of length, mass, and time are the meter (m), kilogram (kg), and second (s), respectively, and are used worldwide by scientists and in many countries for various applications. However, in the United States, the customary units are still widely used by nonscientists, especially in sports and everyday life.
