Final answer:
The balloon fell a distance of 13 yards.
Step-by-step explanation:
The balloon fell a distance of 13 yards.
When an object is dropped, it falls due to the force of gravity pulling it down towards the Earth. In this case, since the location of the balloon after the fall is represented by -13 yards, it means the balloon fell down 13 yards from the window.
It's important to note that the negative sign represents the direction of the fall, not the actual distance fallen. Therefore, the balloon fell a distance of 13 yards.
