Answer 2

Speed: Speed is the distance of a moving object in a given amount of time. Speed is a measure of how fast something is moving. The average speed of an object in a certain time is the distance the object travelled divided by the time.

Velocity: Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.
