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 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)

she does (2/3) floor / ( 1/3 ) hour = 2 floors/hour
(2 floors/hour ) * n hours = 1 floor
n hours = (1/2) hour
(2 floors/hour ) * n hours = 1 floor
n hours = (1/2) hour
n hours = (1/2) hour. Therefore, at this rate, it will take her half an hour to complete the entire floor.
