Question

Jim is standing beside a pool. He drops away from 4 feet above the surface of the water in the pool. The weight travels a total distance of 12 feet down before landing on the bottom of the pool. Explain how you can write a sum of integers to find the depth of the water.

Answer 1

The weight is dropped from 4 feet above the surface. Add -12 to represent the distance the weight falls before it hits the bottom. 4+(-12)=8. The water is 8 feet deep.
