Here's the breakdown of how average velocity works for a bicycle moving at a constant speed and direction:

* Constant Speed and Direction: This means the bicycle is traveling in a straight line without changing its pace.

* Average Velocity: Average velocity is calculated by dividing the total displacement (change in position) by the total time taken.

Key Points:

* Displacement: The change in position from the starting point to the ending point. Since the bicycle is traveling in a straight line, the displacement is simply the distance traveled.

* Constant Velocity: Because the speed and direction are constant, the average velocity is the same as the instantaneous velocity (velocity at any given moment).

Therefore, the average velocity of a bicycle going at a constant speed in a direction is simply its constant speed in that direction.
