If Iris completes 2/3 of the floor in 1/3 of an hour, it means she covers 2/3 / (1/3) = 2/3 * 3/1 = <<2/3/(1/3)=2>>2 times the length of the gym in one hour.
Since she needs to cover the entire floor, which is 3 times the length of the gym, it will take her 3/2 * 1 = <<3/2*1=1.5>>1.5 hours. Answer: \boxed{1.5}.
Iris is asked to sweep the gymnasium floor after a basketball game. This requires her to push a sweeper from one end of the gym to the other and repeating the pattern until she has covered the entire floor. She completes 2/3 of the floor in 1/3 of an hour. At this rate, how long will it take her to complete the entire floor
