question

At the county fair, Grace took a ride in a hot-air balloon. It was a tethered balloon, which means the balloon stayed tied to the ground so that it didn't drift too high or too far. Grace floated up into the sky until the tether was fully unrolled. She stayed up there a while enjoying the scenery, and then she came back down.

Which graph could show Grace's height above ground over time?

solution

You want to find the graph that could show Grace's height above ground over time. So, consider each part of the story and what the graph should show.

Since Grace floated up into the sky, her height above the ground increased steadily. The graph should show an increasing

segment.

She stayed up there while enjoying the scenery …

Grace stayed in the air for a while, tethered to the ground, so her height above the ground did not change. The graph should show a horizontal

segment.

… and then she came back down.

Grace came back down to the ground, so her height above the ground decreased steadily until it was 0 feet. The graph should show a decreasing

segment.

This graph shows all of the parts of the story in order:
