Answer:
One pipe drains 140 L/min and the other pipe drains 190 L/min
Step-by-step explanation:
Assume that the pipe which releases less is x L/min
∵ One pipe releases x L/min
∵ Other pipe releases 50 L/min more than it
∴ The other pipe releases x + 50 L/min
∵ Water is being drained out of a tank through these 2 pipes
∵ Water is being drained at rate 330 L/min through them
- Add their rates and equate the sum by 330
∴ x + x + 50 = 330
- Add the like terms in the left hand side
∴ 2x + 50 = 330
- Subtract 50 from both sides
∴ 2x = 280
- Divide both sides by 2
∴ x = 140
∵ x represents the rate of one pipe and x + 50 represents the
rate of the other pipe
∴ One pipe drains 140 L/m
∴ Other pipe drains 140 + 50 = 190 L/min
