What was the runner's average speed? What is the average velocity? 2.What is the difference between speed and velocity? O A) Velocity contains information about the direction of motion while speed does not. B) Speed is measured in mph, while velocity is measured in m/s. The concept of speed applies only to objects that are neither speeding up nor slowing down, while velocity applies to every kind of motion. Speed is used to measure how fast an object is moving in a straight line, while velocity is used for objects moving along curved paths. D) E) Speed is an average quantity while velocity is not.
