The Water From One Outlet, Flowing At A Constant Rate, Can Fill The Swimming Pool In 9 Hours. The Water From Second Outlet, Flowing At A Constant Rate Can Fill Up The Same Pool In Approximately In 5 Hours. If Both The Outlets Are Used At The Same Time, Approximately What Is The Number Of Hours Required To Fill The Pool? |

Answer» Assume tank capacity is 45 Liters. Given that the FIRST pipe fills the tank in 9 HOURS. So its capacity is 45 / 9 = 5 Liters/ Hour. Second pipe fills the tank in 5 hours. So its capacity is 45 / 5 = 9 Liters/Hour. If both pipes are opened TOGETHER, then combined capacity is 14 liters/hour. To fill a tank of capacity 45 liters, both pipes takes 45 / 14 = 3.21 Hours.
