Respuesta :
Since Mary drew distance vs time graph, let's check all legs of her journey and see in which one the time passes but distance is static.
- Leg 1: Rode bike for first mile: Definitely distance changes with time.
- Leg 2: Stopped at traffic light: Here, time passes but she doesn't move and thus distance covered is same for that time.
- Leg 3: Walked bike across street: Here she covered short distance with respect to time.
- Leg 4: Rode bike one more mile at constant speed: Definitely here distance changes with time.
As can be seen from the 4 legs discussed above, Leg #2 is when Mary's distance doesn't change.
