First graph: The distance the jogger ran is on the vertical axis, and the jogger ran 1400 m in 15 minutes, which we can see from the graph, because at the time of 15 minutes on x axis (time) is equivalent to the 1400 m on y axis (distance).
Second graph: From minute 6 to minute 8 we can see that the value is constant in the matter of distance, due to that fact we know that the jogger wasn't moving in these two minutes, he was resting.
