Answer:
1.Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. ... An object with no movement at all has a zero speed.
2.You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time.
