Answer:
rate of flow of hot water = 480 L/hour
and rate of flow of cold water = 720 L/hour
Step-by-step explanation:
Suppose rate of flow of hot water = x
and rate of flow of cold water = y
Given 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 question
Equation 1
2x = 3y
Equation 2
x + y = 1200
x = 1200 - y
put this value of x in equation1
2(1200-y) = 3y
2400 - 2y = 3y
2400 = 5y
y = 480
x = 3(480)/2
x = 720
