Hi

2 open pipes fill a tank together in 6min. one pipe alone fills a tank in 9min.

 find time for second pipe alone.

Let x represent the time for second pipe alone

Question states*** per min the Equalizer

   1/9 + 1/x = 1/6

Solving for x by mulitplying thru with 54x, so as all denominators= 1

   6x + 54 = 9x

       54 = 3x

        x = 18min, the time for second pipe alone

CHECKING our Answer***

 2/18 + 1/18 = 3/18 = 1/6
