The graph shows Jack's distance from his home compared to time. Which scenario could best fit the graph?

• Jack leaves his home, walking up a hill behind his house. He stops and takes a break, then continues up the hill until he reaches the top. He then continues down the other side.

• Jack and his dog leave the house jogging. They stop at the dog park for a while and then continue on around the block for a short distance before turning around and running back home.

• Jack leaves his house and starts his daily run by picking up speed. He then holds a constant speed for a little while before he begins to accelerate even more. He suddenly feels a leg cramp and very quickly slows down to a stop.

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.
