Two taps, A and B, working together, take x hours to fill a tank. If tap B alone takes b hours to fill the tank, how long will it take to fill the tank after tap B is turned off?
This is a math problem related to the time it takes for two taps to fill a tank
The problem involves calculating the individual work rates of each tap and then using them to determine the time it takes to fill the tank after one of the taps is turned off

Se a torneira A e a torneira B juntas levam x horas para encher um tanque, e a torneira B sozinha leva b horas para encher o tanque, então a torneira A sozinha levará (xb)/(x-b) horas para encher o tanque depois que a torneira B for desligada.
