Question

Use the story and the position vs. time graph to complete the activity.

An elevator in a hotel starts at ground level. It rapidly moves up to the third floor, where it stops to unload passengers. The elevator then descends to the basement at a slower speed than before.

Line graph of elevator position over time. Vertical axis: floors from the basement to the third. Horizontal axis: time. Segments A, B, and C show motion.

In 1–2 sentences, identify whether or not the graph correctly represents the story. Explain your answer.

Answer 1

Yes. Segment A is a steep upward line from ground to the third floor (rapid ascent), segment B is horizontal at the third floor (stopped), and segment C slopes downward toward the basement with a smaller slope magnitude than A (slower descent).
