Question

За 6 мин в трубу поступило на 300 л больше воды, чем через вторую трубу за 3 мин. Если первую трубу открыть на 4 мин, а вторую на 2 мин, то поступит 2200 л воды. Сколько воды в минуту поступает через первую трубу? СРОЧНО!!!!!!!

Answer 2

#### Problem Analysis We are given two pipes, and we need to determine the rate at which water flows through the first pipe. We are given the following information: - In 6 minutes, 300 liters more water flows through the first pipe than through the second pipe. - If the first pipe is open for 4 minutes and the second pipe is open for 2 minutes, a total of 2200 liters of water flows through both pipes. We need to find the rate at which water flows through the first pipe in liters per minute. #### Solution Let's assume that the rate at which water flows through the second pipe is x liters per minute. Then, the rate at which water flows through the first pipe is (x + 300) liters per minute. We can set up the following equations based on the given information: - Equation 1: (x + 300) * 6 = x * 3 + (x + 300) * 4 (since in 6 minutes, 300 liters more water flows through the first pipe than through the second pipe) - Equation 2: (x + 300) * 4 + x * 2 = 2200 (since if the first pipe is open for 4 minutes and the second pipe is open for 2 minutes, a total of 2200 liters of water flows through both pipes) Let's solve these equations to find the value of x, which represents the rate at which water flows through the second pipe. #### Calculation Simplifying Equation 1: 6x + 1800 = 3x + 4x + 1200 6x + 1800 = 7x + 1200 6x - 7x = 1200 - 1800 -x = -600 x = 600 Substituting the value of x into Equation 2: (600 + 300) * 4 + 600 * 2 = 2200 900 * 4 + 600 * 2 = 2200 3600 + 1200 = 2200 4800 = 2200 #### Answer Based on the calculations, we have obtained an inconsistent result, which means there is no solution that satisfies both equations. Therefore, we cannot determine the rate at which water flows through the first pipe with the given information. Please let me know if there is anything else I can help you with.
