#1/2# of a minute

Explanation:

#1/3# of the bottle was filled in #1/6# of a minute.

We want to achieve #3/3 = 1# of the bottle filled, as this will mean the bottle is full.

Since #3/3 = color(blue)(3)xx1/3#, we can find the total time as:

#color(blue)(3)xx1/6 = 3/6 = 1/2#.

So it will take #color(green)(1/2)# of a minute to fill the bottle.
