a position versus time graph is shown below.
a position versus time graph is shown with y-axis labeled position in meters north up to 20 and x-axis labeled time in seconds up to 10. a line connects points 0, 0 and 1, 4. a horizontal line connects points 1, 4 and 4, 4. a line connects points 4, 4 and 6, 10. a horizontal line connects points 6, 10 and 8, 10. a line connects 8, 10 and 9, 14, and then 10, 15.
