Question 1006200
Use rate unit as POOL per MINUTES.


<pre>
                RATE

Garden Hose      {{{1/(13.5x)}}}

Fire Hose        {{{1/x}}}

BOTH             {{{1/107}}}
</pre>


To try to make the two separate rates relationship clearer, try to compare their rates and see how the comparison agrees with the description.


When that is understood, solve  for x, in  {{{1/(13.5x)+1/x=1/107}}}.
