Question

A driver descends 20 feet in the water from the boat at the surface of a lake. he then rose 12 feet and descends another 18 feet . At this point what is his depth in water?​

Answer 1

Step-by-step explanation:

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
