To solve this problem, we can use the formula:
1 / time taken by Anita + 1 / time taken by Chao = 1 / time taken when working together
1 / 8 + 1 / 6 = 1 / x
Simplify the equation:
1/8 + 1/6 = 3/24 + 4/24 = 7/24
1/x = 7/24
x = 24 / 7
Therefore, Anita and Chao working together can clean a typical pool in approximately 3.43 hours.
1 / time taken by Anita + 1 / time taken by Chao = 1 / time taken when working together
