Calculation:
To find the time taken to fill the tank when all three pipes are opened together, we need to calculate the combined rate at which they fill or empty the tank.
Rate of filling for Pipe A: 1/5 tank/hour
Rate of filling for Pipe B: 1/6 tank/hour
Rate of emptying for Pipe C: -1/12 tank/hour (negative because it empties the tank)
Combined rate: (1/5 + 1/6 - 1/12) tank/hour = 12/60 + 10/60 - 5/60 = 17/60 tank/hour
Time taken to fill the tank:
Time = 1 / Combined rate
Time = 60 / 17
Time ≈ 3.53 hours
Therefore, the tank will be filled in approximately 3.53 hours when all three pipes A, B, and C are opened together.
