Here are a class's results for a paper cup let go down a slide from two shelf heights, three runs each. How many centimeters farther did the cup slide on its longest high-shelf run than on its shortest high-shelf run? Type the number.

Answer: 6

The longest high-shelf run was 46 centimeters.
The shortest high-shelf run was 40 centimeters.
46 − 40 = 6, so the difference is 6 centimeters.
So the cup slid 6 centimeters farther on its longest high-shelf run.
