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

Answer: 18 feet

Explanation:

First, he starts at 18 feet, and goes down 32 feet. 18-32=-18
