Question

Garrett must inspect a bridge that goes over a river. He begins 18 feet above water level to inspect the lighting, descends 32 feet to inspect the base of the bridge underwater, then descends another 4 feet to check on the concrete anchoring the base. Which best represents Garrett’s position with respect to the water level?

–54 feet

–30 feet

–18 feet

–10 feet

Answer 1

you start at 18 feet, go down to -14, go down 4 feet to -18 feet or C

Answer 2

Answer: –18 feet

Explanation:

Given: Garrett begins 18 feet above water level to inspect the lighting, descends 32 feet to inspect the base of the bridge underwater, then descends another 4 feet to check on the concrete anchoring the base.

Then using integers, the expression which represents Garrett’s position with respect to the water level is given by :-

`+18-32-4=-18`

Hence, Garrett’s position with respect to the water level =-18 feet.
