Answer:

The location will be at
- 28(1)/(8) units.

Explanation:

A scuba diver descended at a rate of
2(1)/(4) units per second.

Now, if 0 represents the surface of the water and distances below the surface are negative, then after
12(1)/(2) seconds the location of the diver will be given by the followings :

In one second the diver descends by 2.25 units depth.

So, in 12.5 seconds the diver will descend by
(2.25 * 12.5) = 28.125 units i.e.
28(1)/(8) units depth.

Therefore, the location will be at
- 28(1)/(8) units. (Answer)
