Hello!

The answer would be #3:

3. Velocity has both speed and direction

The expressions “60 mph” or “5 ft/s” are examples of speed because of their lack of direction. On the other hand, the expressions “60 mph south” or “5 ft/s upward” are examples of velocity because they include a direction.

I hope this helps!

The Correct answer to this question for Penn Foster Students is: Direction
