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 2/3 of the floor in 1/3 of an hour.
Let's set up the proportion:
(2/3) / (1/3) = x / 1
Simplifying the left side of the proportion:
(2/3) / (1/3) = (2/3) * (3/1) = 2
So, the proportion becomes:
2 = x / 1
Cross multiplying, we get:
2 * 1 = x
2 = x
Therefore, it will take Iris 2 hours to complete the entire floor.
The correct answer is:
1 hour
