Kristen and Gigi are riding in hot air balloons. They start 500 feet above the ground. Kristen’s balloon rises 225 feet, falls 105 feet and then rises 445 feet. Every time Kristen’s balloon travels up and down, Gigi’s balloon travels 15feet farther in the same direction. Then both balloons stop moving so a photographer on the ground can take a picture
