There are two pipes. Twice the water flow in the hot water pipe is equal to three times the water flow from the cold pipe. Combined it equals 1200 L/hour. What is the flow in each pipe?

Answer: rate of flow of hot water = 480 L/hourand rate of flow of cold water = 720 L/hourStep-by-step explanation:Suppose rate of flow of hot water = x and rate of flow of cold water = yGiven that,Twice the water flow in the hot water pipe is equal to three times the water flow from the cold pipe.Combined it equals 1200 L/hour. According to the questionEquation 12x = 3yEquation 2x + y = 1200x = 1200 - yput this value of x in equation12(1200-y) = 3y2400 - 2y = 3y2400 = 5yy = 480x = 3(480)/2x = 720
