Answer

Answer:

C. A dog runs an average of 8 mph.

Explanation:

Step1: Define speed

Speed is a scalar quantity that refers to "how fast an object is moving." It is measured by the distance traveled per unit of time.

Step2: Analyze each option

  • Option A: "Cindy biked westward at 30 km/h" has a direction (west - ward), so it is velocity (a vector quantity), not speed.
  • Option B: "A rock is to the left of a flower - pot" is a position description, not related to speed.
  • Option C: "A dog runs an average of 8 mph" only gives the rate of motion (distance per time) without a specific direction, which is an example of speed.
  • Option D: "Leo lives 2 miles north of Andre" is a position - related statement, not speed.
