Answer: Ans. one: 27.5 min. on each floor | Ans. Two: 55 min on first floor. | Ans. Three: 55 min on second floor.

Explanation:

Ans. One: Say there are the same amount of windows on each floor. She takes the same amount of time to wash each floor's windows. 55 / 2 = 27.5.

Ans. Two: There are no windows on the first floor. It takes her 55 min. in total. 55 min. to do one floor.

Ans. Three: There are no windows on the second floor. It takes her 55 min. in total. 55 min. to do one floor.

Hope this helps! <3
