Diver A is lowered 28 feet below the surface of the ocean. She swims down another 6 feet. What integer expresses her position compared to the ocean's surface?
28 + 6 = ?
since it is below the surface should it be -28 + -6 = -34?
To find the diver's position compared to the ocean's surface, we need to subtract the distance she has descended from the original depth of 28 feet.
Given that Diver A is lowered 28 feet below the surface and then swims down another 6 feet, the total distance she has descended is 28 + 6 = 34 feet.
To express the diver's position compared to the ocean's surface, we need to subtract the total distance descended from the surface level, which is 0 feet. Therefore, the integer that expresses the diver's position is 0 - 34 = -34.
So, the diver's position compared to the ocean's surface is -34 feet.
