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.

A line graph shows the motion of an elevator as it goes up and down. The vertical axis lists various floors of the building. The horizontal axis shows time. A line sloping upward from the ground floor to the third floor is labeled, A. A line parallel to the horizontal axis at the third floor is labeled, B. A line sloping downward from the third floor to the basement is labeled, C.

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

Yes, the graph correctly represents the story. It shows the elevator rapidly moving up to the third floor, stopping at the third floor, and then descending to the basement at a slower speed.

Based on the description, the graph correctly represents the story. The upward sloping line from the ground floor to the third floor represents the elevator going up rapidly, the horizontal line at the third floor represents the elevator stopping to unload passengers, and the downward sloping line from the third floor to the basement represents the elevator descending at a slower speed.

To determine if the graph correctly represents the story, you need to compare the description of the elevator's motion with the information provided in the graph. First, check if the graph shows the elevator starting at ground level, moving rapidly up to the third floor, and then descending to the basement at a slower speed. Next, confirm if the labeled lines on the graph match the described motions (i.e., line A sloping upward, line B parallel to the third floor, and line C sloping downward). Based on this comparison, you can determine if the graph accurately represents the story.
