Question

Need help quick!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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)? 10,000 ÷ 2,000 -10,000 ÷ 2,000 -10,000 ÷ (-2,000) 10,000 ÷ (-2,000)

Answer 1

-10,000 / -2000, although 10,000/2000 gives the same answer.

Explanation:

The equations -10,000/2000 and 10,000/-2000 are negative, and negative days do not make sense, thus eliminating those answers.

Also, she wants to descend 10,000 feet, so that makes it -10,000 int he equation.
