Question 1101758
{{{R*T=V}}}, R depends on how many agents


r. the flow rate of any one faucet
Volume is in tubs
Let x be the unknown time for the second part of the description.


{{{system(16r*10=8,12*r*x=9)}}}

-

{{{r=8/(16*10)}}}

{{{r=1/20}}}

-

{{{x=9/(12*r)}}}

{{{x=3/(4r)}}}

{{{x=(3/4)(1/r)}}}

{{{x=(3/4)*20}}}

{{{highlight(x=15)}}}
