Which option defines speed?

• A. Ability to move your body and/or limbs rapidly.
• B. Ability to balance on one leg.
• C. Ability to coordinate movements quickly.
• D. Ability to exhale quickly.

Answer: (A)

Speed is the rate at which you move your body or its parts. The option that describes moving your body and/or limbs rapidly captures this idea directly, since speed measures how fast movement occurs. Balance on one leg is about stability and control, not how quickly you can move. Coordinating movements quickly concerns timing and sequencing, which is about coordination as well as speed but not the basic definition. Exhaling quickly relates to breathing, not movement speed. In practical terms, speed can be thought of as distance covered over time, a measure of how fast actions happen.
