Question 1173939
.
<pre>

The volume of the 1st aquarium is   {{{V[1]}}} = 12*13*14 = 2184 cubic inches.


The volume of the 2nd aquarium is   {{{V[2]}}} = 22*24*25 = 13200 cubic inches.



Obviously, at the constant filling rate, the time to fill the volume is proportional to volume.


THEREFORE, you can write this proportion


    {{{V[2]/V[1]}}} = {{{t/5}}},


where "t" is the unknown time filling 2nd aquarium.


From the proportion,


    t = {{{(5*V[2])/V[1]}}} = {{{(5*13200)/2184}}} = 30.22 minutes,  or about 30 minutes and 13 seconds.

Solved.
