Baker is a balloonist who has a balloon-tour company on the North Rim of the Grand Canyon. One day he took his balloon up to ft to give his guests a bird’s-eye view of the entire canyon. Then he lowered the balloon to the bottom of the canyon so his guests could swim in the Colorado River. The river is over a mile (
ft) below the North Rim. After lunch, the tourists all got back aboard the balloon. The balloon carried them up to the South Rim,
ft above the river.

Draw a diagram that shows the balloon’s elevation throughout the day.

Label the North Rim as zero, since it is the starting place. Then find out the elevation of the balloon tourists’ stopping place (the South Rim) relative to their starting place (the North Rim).
