Which statement is true about speed and velocity?

Explanation:
Speed tells you how fast something is moving, and it is a scalar—only magnitude, no direction. Velocity, on the other hand, includes both speed and direction, so it is a vector. That’s why the statement that speed is the magnitude of motion and velocity includes direction is the true one. For example, a person moving at 3 m/s to the east has a speed of 3 m/s and a velocity of 3 m/s east. The other ideas fail because velocity is not a scalar, speed does not include direction, and speed and velocity are not identical.
