Question

Four years ago, the water in the apartment complex pool was emptied using a single pump. That took 33 hours. To get the job done more quickly this year, the apartment manager is going to use an additional pump that would take 22 hours to empty the entire pool on its own. If the pool contains 99,000 gallons of water, how much faster will the pool empty using both pumps at the same time than it did four years ago?
