Question

is the distance traveled during a specific unit of time.

Explanation:

The question is about a term that represents the distance traveled in a specific unit of time. In physics (a subfield of Natural Science), the concept of speed (or velocity, but speed is scalar and focuses on distance over time) is defined as the distance covered per unit time. So the term here should be "Speed" (or "Velocity" depending on context, but speed is more about distance over time without direction).

Answer:

Speed
