This is the problem: "A mountain climber is at an elevation of $10,000$ feet. If she descends $2,000$ feet a day, which equation would be used to show how many days it will take to reach sea level ($0$ feet)?"
My online school says the problem looks like this; $10,000 ÷ 2,000$ but I thought it should be $-2,000$ since climber is descending.
The online teacher said this, "It would not be a negative number since we are given $10,000$ feet and $2,000$ each day. This answer is correct."
