Answer

Explanation:

Step1: Recall velocity definition

Velocity is a vector - it has both magnitude (speed) and direction.

Step2: Analyze option A

A parked car has zero velocity, a car moving in circles has non - zero velocity and changing direction, not the same.

Step3: Analyze option B

The magnitudes (40 mph and 50 mph) are different, so not the same velocity.

Step4: Analyze option C

The directions (east and west) are opposite, so not the same velocity.

Step5: Analyze option D

Both Valerie and Owen have the same speed (8 km/h) and the same direction (south), so they have the same velocity.

Answer:

D. Valerie rides her bike south at 8 kilometers per hour. Owen jogs south at 8 kilometers per hour.
