Answer 1

To determine the location of the basement woodshop, we can start with Arthur's initial height above ground and subtract the distance he descends.

Arthur is initially at 24.3 feet above ground. He descends 39.9 feet to the basement:

\[ \text{Final position} = \text{Initial position} - \text{Descent} \] \[ \text{Final position} = 24.3 - 39.9 \]

Calculating that gives:

\[ 24.3 - 39.9 = -15.6 \text{ feet} \]

This means the basement woodshop is located 15.6 feet below ground level.

The number that best describes the location of the basement woodshop is:

−15.6 feet.
