Answer

Brief Explanations:

Between minutes 9 and 15, the speed - time graph shows a horizontal line at 8 miles per hour. A horizontal line on a speed - time graph indicates that the speed is constant. When speed is constant, the object is moving at a steady rate without acceleration or deceleration. This is most likely to happen when the object is on level ground and maintaining its speed.

Answer:

D. He was on level ground, maintaining his speed.
