If Iris completed 23 of the floor in 1/3 of an hour, it means she completed 1/13 of the floor in 1/3 * 13 = 4/3 hours.
Since 1/13 of the floor takes 4/3 hours to complete, the entire floor will take 13/1 * 4/3 = <<13/1*4/3=17.333>>17.333... hours to complete.
It will take her approximately 17 hours and 20 minutes to complete the entire floor. Answer: \boxed{17}.
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 23 of the floor in 13 of an hour. At this rate, how long will it take her to complete the entire floor?

what is 17 hours and 20 min in a fraction
To convert 17 hours and 20 minutes into a fraction, we need to find the equivalent fraction of 20 minutes in terms of hours. Since there are 60 minutes in an hour, we divide 20 minutes by 60 to get its equivalent fraction in hours:
20 minutes รท 60 minutes/hour = 1/3 hour
Therefore, 17 hours and 20 minutes is equivalent to 17 + 1/3 = 51/3 + 1/3 = 52/3 hours.
So, 17 hours and 20 minutes is equal to the fraction 52/3.
20 minutes รท 60 minutes/hour = 1/3 hour
Therefore, 17 hours and 20 minutes is equivalent to 17 + 1/3 = 51/3 + 1/3 = 52/3 hours.
So, 17 hours and 20 minutes is equal to the fraction 52/3.

To find out how long it will take Iris to complete the entire floor, we can set up a proportion using the completed fraction and the time taken.
Since Iris completed 23 of the floor in 1/3 of an hour, we can write the proportion as:
23/1 = x/1/3
To solve for x, we can multiply both sides of the equation by 1/3:
(23/1) * (1/3) = x
23/3 = x
Therefore, it will take Iris 23/3 hours to complete the entire floor. This can also be expressed as 7 2/3 hours.
So the answer is: 7 2/3 hours
