The slope of the displacement vs. time graph gives the average velocity of the bicycle at the constant speed in a constant direction. Thus, option A is correct.
What is average velocity?
Average velocity is defined by the shift in the position of the object from the original place to another but the speed and the direction have to be constant.
The graph showing the slope of displacement and time best describes the average velocity, as it is shown as,
Average velocity = displacement ÷ change in time
Therefore, the slope of displacement shows the average velocity.
