7. Example
Kendra leaves home to ride her bike. She travels for several minutes at a medium speed. She then stops for a short while to check her pockets when she realizes that she dropped her money. She speeds back toward home for a few minutes until she finds the money on the street. She stops for a moment to pick it up and secure it in a safe place. She is relieved so she continues on at a slow, relaxed pace.
