Question 1032200
I'm assuming the drain is left 1/2 open
The drain being 1/2 open, means the tank
will take twice as long to drain, or 22 hrs
-----------------------------------
Let {{{ t }}} = time in hrs to fill the tank
{{{ 1/9 - 1/22 = 1/t }}}
Multiply both sides by {{{ 9*22 = 198 }}}
{{{ 22 - 9 = 198/t }}}
{{{ 13 = 198/t }}}
{{{ t = 198/13 }}}
{{{ t = 15.231}}}
It will take 15.231 hrs to fill the tank
---------------
check:
{{{ 1/9 - 1/22 = 1/t }}}
{{{ 1/9 - 1/22 = 1/15.231 }}}
{{{ .111 - .0455 = .06565 }}}
{{{ .0656 = .06565 }}}
close enough
