The tub can also be emptied when the plug is pulled out, in 4 minutes. Farley ran the hot water in his tub for 3 minutes, then both the cold and hot water together for 1 minute, and then with the two taps still running, he accidentally pulled the plug. How long, did it take in minutes, for the tub to fill after the plug was pulled? </SPAN>\n" );
