Question 885113
Fill Rate for Both Together:    {{{1/t+1/(2t)}}} baths per minute.


How much bath filled in 1 minute?
{{{(1/t+1/(2t))*1}}}, amount of bath.
{{{2/(2t)+1/(2t)}}}
{{{3/(2t)}}} amount of baths in 1 minute.


If you want to know the time to fill 1 bath, then you use another variable, say x.
{{{(1/t+1/(2t))x=1}}}, but we cannot find a unique t and x combination because this is only one equation in two unknowns.


You can only get the <b>fraction</b> of bath filled in one minute as  {{{highlight(3/(2t))}}}.
