Edited by A Warlock: 4/26/2015 3:59:56 AM2/3 of the water in a pool can be pumped out within 7.5 minutes by a particular pump. The pump worked for 0.15 hours and stopped. When it stopped, 25 m3 of water still remained in the pool. How much of the water was in the pool before the pump started working? [spoiler]I was to lazy to type it...[/spoiler]
