The diver started at 82 feet below the surface.
After the first step of 15 feet, the diver would be at:
82 - 15 = 67 feet below the surface
After the second step of 15 feet, the diver would be at:
67 - 15 = 52 feet below the surface
After the third step of 15 feet, the diver would be at:
52 - 15 = 37 feet below the surface
After the fourth step of 15 feet, the diver would be at:
37 - 15 = 22 feet below the surface
After the fifth and final step of 15 feet, the diver would be at:
22 - 15 = 7 feet below the surface
Therefore, the diver's new position in relation to the water surface is 7 feet below the surface.
