Question

At your construction job, you're standing on a ladder at ground level. First, you climb down 7 feet to see the basement. Then you climb up 22 feet to see the second floor. Later, you climb down 9 feet. How high above or below the ground are you?

Answer 1

(-7) + 22 + (-9) = 6

Answer 2

We will reach 6 feet below the ground.

Explanation:

We are given that,

The sequence of movement on the ladder is given by,

1. Climb down 7 feet down

2. Climb up 22 feet up

3. Climb down 9 feet down.

So, we see that,

The distance after the sequence of movements = (-7) + 22 + (-9) = 6 feet.

From the figure, we see that,

We will reach 6 feet below the ground.
