On the way to her babysitting job, Mary rode her bike for the first mile. She stopped at a traffic light and waited a few minutes for the traffic light to turn green. She then walked her bike across the street and up a short steep hill. Finally, she rode the bike at a constant speed for one more mile. If Mary created a graph of her time and distance, which statement describes the part of her graph that would show no change in distance?

Welcome to QuestionCove! May I ask what are your answer choices?

When Mary was riding her bike she was moving at a constant speed, this means her distance was increasing as well. During this time there was change. She had to stop at a stoplight, due to this she had to resort to a m/s of 0 meaning no change whatsoever. Moving causes change, while pauses cause no change.
