-232 ft

Step-by-step explanation:

Going further down from where she is will be negative and going up from where she is will be positive. So if she starts at - 480 and swims upwards, she is moving in a positive direction. The addition problem is

-480 + 248

which comes out to - 232. She is still 232 feet below the surface.
