The graph shows Rosie's speed compared to time. Which scenario best fits the graph?

• Rosie sets off quickly on a run picking up speed before she holds a constant speed for a while. She then begins to slow down and then stops completely.

• Rosie ran up a hill, walked across the top, and then walked back down to the other side.

• Rosie left home walking fast, stopped to buy an ice cream cone, then walked at a slower pace back to her house.

• Rosie increases speed slowly, then holds a constant speed, then decreases her speed quickly, coming to a complete stop.
