Cindy and jena, working together, can clean the house in 66 hours. working alone, jena takes twice as long as cindy. how many hours does it take cindy to clean the house alone? round your answer to two decimal places, if needed.

Let Cindy taking total time cleaning the house = C

Let Jena taking total time cleaning the house = J

As per given in question, they both takes 66 hrs to clean the house together means

(1 / C) + (1 / J) = (1 / 66)

jena takes twice as long as cindy means C = 2 J

replacing the value

1 / C + 1/ 2C = 1/66

3/2C = 1/66

Cross multiplying

3 * 66 = 2 C * 1

198 = 2 C

Dividing by 2

198 / 2 = C

C = 99 hrs

It means Cindy will tae 99 hrs to clean the home alone. : Answer
