Answer 1

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. How many feet above the ground is the plane?

In this case, the ascent and descent are equal in magnitude but opposite in direction, resulting in a net change of 0 feet above the ground.
