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?(1 point)

Answer 1

To find out how long it takes Iris to complete the entire floor, we can set up a proportion.

Let x be the time it takes for her to complete the entire floor.

We know that Iris completes 2/3 of the floor in 1/3 of an hour, so we can set up the proportion:

(2/3) / (1/3) = 1 / x

Simplifying the left side of the equation:

(2/3) * (3/1) = 1 / x

2 = 1 / x

To solve for x, we can take the reciprocal of both sides:

1/2 = x

So, it will take her 1/2 hour or 30 minutes to complete the entire floor.

Therefore, the answer is 1/2 hours.
