A runner is warming up for her event on a circular track with a diameter of 102 m. She starts by walking 1/5 of the way around the track in 177 s, then sprinting the next 3/5 of the way around the track in 127 s, before walking the final 1/5 of the track back to where she started in 178 s. What is the magnitude of the runner's average linear velocity from start to finish of her warm-up lap

no

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
