Answer 1

Upward movement is taken as positive and downward as negative.

Fish intiallin at 125 m below sea level,
so position of fish =-125

then it rises 56,
So position of fish =-125+56=-69

Dives 48 m( below )
Position=-69-48=-117

Rises 25 m
Position=-117+25=-92

The fish's position is 92 meters below the sea level.
