Question

A swimmer is looking for a species of fish along the coast line. She dives 12 feet below the surface of the ocean. Then she dives down 9 more feet. She swims back up 10 feet and down another 6 feet before she finds the species of fish she is looking for. What was the depth at which the swimmer finds the fish?

Answer 1

17 feet

Explanation:

Given

Downward Movements: 12 feet; 9 feet; 6 feet

Upward Movement: 10 feet

Required

Determine the position at which the swimmer got the fish

First, we need to add up the downward movements;

`Downward = 12ft + 9ft + 6ft`

`Downward = 27ft`

Then subtract the upward movement

`Position = Downward - Upward`

`Position = 27ft - 10ft`

`Position = 17ft`
