How to solve a math problem

Assume that the conductivity of the recycled water is divided by the conductivity of the make-up water. It is known that the conductivity of the recycled water is 2000. For the make-up water, one type is fresh water at a flow rate of 20 cubic meters per hour, with a conductivity of 600; the other type is reclaimed water at a flow rate of 30 cubic meters per hour, with a conductivity of 750. How should this be calculated?
One type is fresh water at a rate of 20 cubic meters per hour, with a conductivity of 600; the other type is recycled water at a flow rate of 30 cubic meters per hour, with a conductivity of 750. In total, 50 cubic meters of water are added per hour. What is the conductivity of the water that is added?
It seems like it’s just about finding the average, right? (20*600 + 30*750)/50 = 690. I’m not sure if that’s correct.
