Answer 2

Answer:

Average speed:-

The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance. It's a scalar quantity which means it is defined only by magnitude. A related concept, average velocity, is a vector quantity. A vector quantity is defined by magnitude and direction.

Speed:-

Speed is the distance covered by an object in a unit time.

Speed =Distance travelled/time taken

SI unit of speed is metre per second (m/s).
