Answer:
feet
Step-by-step explanation:
The depth of the fish to the surface of water at 1:00 pm = 2 feet
= feet
The depth of the fish to its initial position at 4:00 pm = 3 feet
= feet
The position of the fish with respect to the water's surface at 4:00 pm = the depth of the fish to the surface of water at 1:00 pm + the depth of the fish to its initial position at 4:00 pm
= +
=
=
The position of the fish with respect to the water's surface at 4:00 pm is feet.
