Hello!
To find the increase in depth, we must subtract the initial depth from the final depth. This can can be represented by the following formula:
(change in depth) = (final depth) – (initial depth)
Insert any known values into the equation above and simplify:
(change in depth) = [tex] \frac{3}{4} [/tex] – [tex] \frac{1}{4} [/tex]
change in depth = [tex] \frac{2}{4}[/tex]
We have now proven the change in depth to equal [tex] \frac{2}{4} [/tex]. We know, however, that this fraction can be reduced to a value of [tex] \frac{1}{2} [/tex]. Therefore, the answer to this problem is C.
I hope this helps!
