The situation that describes opposite quantities that when combined would equal 0 is: A plane ascends to 15,000 feet and then descends 15,000 feet. In this scenario, the plane would end up at the same altitude it started from, so it would be 0 feet above the ground.

The situation that describes opposite quantities that when combined would equal 0 is when a plane ascends to a certain height and then descends the same amount. In this case, the plane ascends to 15,000 feet and then descends 15,000 feet.

To calculate how many feet above the ground the plane is, we can subtract the amount it descended from the amount it ascended:

15,000 feet - 15,000 feet = 0 feet

Therefore, after ascending and then descending the same amount, the plane would be 0 feet above the ground.
