Question

a diver descended 20 feet into the water from a boat at the surface of a lake. he then rose 12 feet and descended in his depths in the water ?​

Answer 1

Answer:

- 26

Step-by-step explanation:

Let the initial position of the diver be 0.

Now, the diver descends 20 feet in the water which can be given as -20 feets.

Then he rose 12 feet i.e. +12 feets and he descends another 18 feet i.e. -18 feets.

Now his depth in water = final position = (-20 +12 -18) feets = -26 feets

Therefore, the man is now at 26 feets depth in water.
