Question

Dean Baldus enjoys scuba diving. He dives to 34 ft below the surface of a lake. His partner Jeff​ Balius, dives to 39 ft below the​ surface, but then ascends 18 ft. Find the vertical distance between Dean and Jeff.

Answer 1

The vertical distance between Dean and Jeff is 13 ft below the surface

Step-by-step explanation:

Jeff dove 39 ft below the surface and then ascends 18 ft

-39 - 18 = 21

Jeff is 21 ft below the surface

------------------

Dean is 34 ft below the surface

-34 - (-21) = -13 ft

-----------------

So, Dean and Jeff are 13 feet away from each other (vertical distance).
