Juan goes for a run. After running for 20 minutes, he takes a 5-minute

break. Which graph best represents this?

• 
• 
• 
• 

Look at the distance time graph that shows the motion of a student on a walk.

Which statement best describes the student's motion?

• The student walks slowly at first, then increases their speed, stops, and very quickly returns to the starting point.

• The student walks up a hill at the beginning, and then has a flat surface, and then walks down a hill at the end.

• The student is going faster and faster in the last two minutes.

• The student starts out moving very fast, slows down in the middle of the walk, and then speeds up again at the end.
