Answer 1

Question:

A divers decends 20 feet in the water from the boat at the surface of a lake. He then rose feet 12 feet and decends another 18 feet. at this point what is his depth in water.

Solution:

When a diver descends 20 feet, the depth of water here is 20 feet

The diver then ascends 12 feet;

Depth of water = 20 - 12  

                       $= 8 feet$

The diver then descends another 18 feet

The depth of water here $= 8 + 18$

                                     $= 26 \: feet$

Answer 2

Step-by-step explanation:

$h$

When a diver descends 20 feet, the depth of water here is 20 feet

The diver then ascends 12 feet;

Depth of water = 20 - 12

=8feet

The diver then descends another 18 feet

The depth of water here = 8 + 18=8+18

=26feet

so, 26 feets
