Answer:

Explanation:
We have been given that a diver swims 5.875 feet up to the surface of the water.
Since diver is coming towards surface of water, so the elevation of diver will be positive.
Since diver's position was below water surface before swimming, so the elevation of diver was negative before swimming to the top.
Therefore,
feet represents the divers position in relation to the surface before swimming to the top.
