Explanation:

Step1: Identify the depths

Cora's depth: $35$ feet below surface (so we can think of her position as $-35$ relative to surface, but for height difference, we use absolute depths). Instructor's depth: $90$ feet below surface.

Step2: Calculate the difference

To find how much higher Cora is, we subtract Cora's depth from the instructor's depth (since higher means less deep). So $90 - 35 = 55$.

Answer:

55
