Elevator 1 in an office building moved from ground position to a final position of +12 feet. Elevator 2 in the same building moved from ground to a final position of −15 feet. Which statement best describes the final positions of these two elevators? Elevator 1 is 12 feet above ground level, and Elevator 2 is 15 feet below the position of Elevator 1. Elevator 1 is 12 feet below ground level, and Elevator 2 is 15 feet above the position of Elevator 1. Elevator 1 is 12 feet above ground level, and Elevator 2 is 15 feet below ground level. Elevator 1 is 12 feet below ground level, and Elevator 2 is 15 feet above ground level.

Answer 1

C. Elevator 1 is 12 feet above ground level and Elevator 2 is 15 feet below ground level.

Explanation:

Let's break this down step-by-step

Step 1: Find Position of Elevator 1

This is just a simple addition problem

0 + 12 = 12

Elevator 1 is 12 feet above ground level

Step 2: Find Position of Elevator 2

This time, we use subtraction, since it is -15 feet

0 - 15 = -15

Elevator 2 is 15 feet below ground level

Step 3: Find the best statement

C. Elevator 1 is 12 feet above ground level and Elevator 2 is 15 feet below ground level.
