[AI-generated answer — Bot GPT 3.5]

To find out how long it will take Anita and Chao working together to clean a typical pool, we can use the formula:

1/(time taken by Anita) + 1/(time taken by Chao) = 1/(time taken by both)

1/8 + 1/6 = 1/x

Multiplying through by 24x to clear the denominators:

3x + 4x = 24

7x = 24

x = 24/7

So, it will take Anita and Chao working together approximately 3 3/7 hours to clean a typical pool or 3 hours and 26 minutes.
