Question

Oliver climbed 222 meters of a steep mountain reach the summit. He then rappelled down the other side of the mountain to return to the base. Which integer best represents Oliver's descent? A. -444. B. -222. C. 0. D. 222

Answer 1

B -222

Because he fell/descended 222 meters. And falling or going down produces a negative integer. Also, if you were actually doing the math to try to find where Oliver is currently located, you wouldn't add 222, or 0, or subtract -444. You would subtract 222.

In addition, be aware that the question is asking you an integer to represent a situation, not the answer of where Oliver is.
