Product Pulse

Product Pulse focuses on transforming security awareness by making it engaging, personalized, and effective The problem states that each pump can empty 24 L (from whatever starting amount) in 20 minutes. The rate for each pump is 1.2 L/min. So, a pump running for 30 minutes can pump out 1.2 * 30 = 36 L. The maximum capacity of each tank must therefore be 36 L. Yes, this is correct if the tank is not being refilled at pump 1. No it is not. The information does not tell us what the capacity of the tank is. It only says what a pump can do. It's a limiting statement for how much can be pumped out. The water can be pumped out. It does not state that it is the minimum or maximum which CAN be pumped. It simply states that 'the maximum amount of water that can be pumped out from each tank in 20 minutes (using pump 1, 2 or 3 exclusively) is 24 liters'. From this we can calculate max rate but not max volume. The question is referring to EACH tank. So, 24L is the maximum amount that can be pumped from a tank in 20 minutes. If the tank held 30L of water and a pump has a rate of 1.2 L/min then it would pump out 1.2*20=24 L in 20 minutes. It still would have 6L remaining. BUT the phrasing 'maximum amount that can be pumped out from each tank' means that 24L is the capacity of the tank. Not that it's the maximum rate of the pump. The question states that the max capacity of the tank is 24 L. (Yes I get it. The tank is 24 L big. That means max that can be in it is 24L at any time). So, this means that the maximum capacity of each tank is 24 liters. Yes. This is correct.
