Final answer:
Camilla's position relative to the surface of the pool is 2 feet.
Step-by-step explanation:
Camilla's position relative to the surface of the pool is now 2 feet.
When she pushes off the bottom of the pool and rises 4 feet, she is still at a depth of 2 feet from the surface. This is because her initial depth was 6 feet, and when she rises 4 feet, she reduces her depth by 4 feet.
Therefore, her position relative to the surface of the pool is 2 feet.
