The correct answer is B. "65 mi/hr south" is an example of velocity.

Velocity is a vector quantity that includes both the magnitude (speed) and the direction of an object's motion. It describes how fast an object is moving and in what direction.

Option A, "Speed," is incorrect. While "65 mi/hr" represents the magnitude of the motion, it does not include any information about the direction. Velocity requires both the magnitude and direction to be specified.

Option C, "Acceleration," is also incorrect. Acceleration refers to the rate of change of velocity, not velocity itself. It involves changes in speed, direction, or both, over time. The given statement does not provide any information about changes in velocity or acceleration.

Option D, "Di...
