Final answer:
Pace is the speed at which a runner covers a certain distance over a certain time period. It is calculated by dividing the distance by the time taken. It is an important concept in physics.
Step-by-step explanation:
The pace at which a runner runs can be defined as the speed at which they cover a certain distance over a certain amount of time. Mathematically, pace is calculated by dividing the distance covered by the time taken. For example, if a runner covers 10 kilometers in 1 hour, their pace would be 10 kilometers per hour. Pace is an important concept in physics, as it relates to the speed and motion of objects.
