Questions such as, “How long does a foot race take?” and “What was the runner’s speed?” cannot be answered without an understanding of other concepts. In this section we add definitions of time, velocity, and speed to expand our description of motion.

Both concepts emphasize the importance of understanding how quickly an event occurs, whether it's cars on a track or substances in a reaction.
