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?(1 point)Responses12 hoursStart Fraction 1 over 2 End Fraction hours1121 Start Fraction 1 over 2 End Fraction1 hour1 hour23 hours
To find out how long it will take Iris to complete the entire floor, we can set up a proportion.
We know that Iris completes 23 units of floor in 1/3 of an hour. Let's call the total number of units of floor "x" and the time it takes her to complete it "t".
23/x = 1/3
To solve for x, we can cross multiply:
3 * 23 = x * 1
69 = x
So, the total number of units of floor is 69.
Now, we can set up another proportion to find out how long it will take Iris to complete the entire floor:
23/69 = t/1
To solve for t, we can cross multiply:
69 * t = 23 * 1
69t = 23
t = 23/69 = 1/3
So, it will take Iris 1/3 of an hour to complete the entire floor, which is equivalent to 20 minutes.

To find out how long it will take Iris to complete the entire floor, we can set up a proportion.
We know that she completes 23 units of the floor in 1/3 of an hour.
Let's call the time it takes her to complete the entire floor "t" hours.
Therefore, we can set up the following proportion:
23/1/3 = x/1
To solve for x (the time it takes her to complete the entire floor), we need to multiply both sides of the equation by 3/1:
(23/1) * (3/1) = x * 1
69 = x
So, Iris will take 69 hours to complete the entire floor.
Wrong
Apologies for the incorrect response.
To find out how long it will take Iris to complete the entire floor, we can set up a proportion.
We know that she completes 23 units of the floor in 1/3 of an hour.
Let's call the time it takes her to complete the entire floor "t" hours.
Therefore, we can set up the following proportion:
23 units / (1/3 hour) = Entire floor / t hours
To solve for t (the time it takes her to complete the entire floor), we can multiply both sides of the equation by t:
23 units / (1/3 hour) * t = Entire floor
Simplifying, we get:
(23 units * 3 hour) / 1 = Entire floor * t
69 units = Entire floor * t
To solve for t, we can divide both sides of the equation by the entire floor:
69 units / Entire floor = t
Since the entire floor is not specified in the question, we cannot determine the exact time it will take Iris to complete the floor without that information.
answer the question
Apologies for the confusion. Let's solve the problem again.
Iris completes 23 units of the floor in 1/3 of an hour.
To find out how long it will take her to complete the entire floor, we can set up a proportion:
23 units / (1/3 hour) = Entire floor / t hours
To solve for t (the time it takes her to complete the entire floor), we can use cross-multiplication:
23 units * t hours = (1/3 hour) * Entire floor
Simplifying, we get:
23t = (1/3) * Entire floor
To find the entire floor, we need more information. If we have the total number of units or the size of the gymnasium floor, we can substitute that information into the equation.
For example, if the entire floor is 46 units, we can solve for t as follows:
23t = (1/3) * 46
23t = 46/3
t = (46/3) / 23
t = 2/3
So, if the entire floor is 46 units, it will take Iris 2/3 of an hour to complete it.
