To solve this question, we need to use integers to express different altitudes. We can sketch each situation as follows:

To find the depth at which each person rested, we need to algebraically sum all these altitudes.

Jim:

-8 -18 + 5 - 9 = -30. He rested at 30 feet below the surface.

Carla:

-16 + 5 - 18 = -29. She rested at 29 feet below the surface.

Therefore, Jim rested at a greater depth (30 feet below the surface).
