Iris is asked to sweep the gymnastics 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?

Answer 1

Since Iris completes 2/3 of the floor in 1/3 of an hour, this means she can complete 1/3 of the floor per 1/3 hour. Therefore, she can complete the entire floor in 1 hour. Answer: \boxed{1}.
