Question

which statement about speed and/or velocity is true?
speed is measured over time.
speed is constant.
velocity has both speed and direction.
speed has direction and velocity.

Explanation:

Speed is a scalar quantity representing the rate of motion without considering direction. Velocity is a vector quantity, which means it has both magnitude (speed) and direction. Speed is calculated as distance traveled per unit time, but it's not always constant. And speed itself has no direction.

Answer:

C. Velocity has both speed and direction.
