Question

A dive ring on the bottom of the pool is 10 feet below the surface of the water. Sabine dives down and brings the ring back to the surface. What integer represents the dive ring's final position with respect to the surface of the water?

Answer 1

0

Explanation:

Given

`Ring's\ Position = 10\ feet`

Required

Determine its new position

Because the ring was initially below the surface of the pool;

Its initial position is

`Position = -10\ feet`

Taking it to the surface of the pool;

It means, the ring travels a distance of:

`Distance = +10\ feet`

It's final position is the summation of its initial position and distance travelled;

`Final\ Position = Initial\ Position + Distance\ Traveled`

`Final\ Position = -10\ feet + 10\ feet`

`Final\ Position = 0\ feet`

Hence, 0 represents its new position with respect to the surface of the water
