Okay. So, we could solve this the longer way, but we can solve this in an easier way. Let's put the equation like this: 981 + 15.25m = 42.5m. We are doing this, because the first pool already has hundreds of liters in them and is being added, and the second pool has no liters in there yet, but is being added in there. First, let's subtract 15.25 from 42.5. When we do that, we get 981 = 27.25m. Now, let's divide each side by 27.25 to isolate the m. When you do that, you get 36. Let's try it out to see if it works. 15.25 * 36 is 549. 549 + 981 = 1,530. 42.5 * 36 = 1,530. 1,530 = 1,530. There. m = 36. Here are the answers for you to read easier.
Amount of minutes: 36 minutes
Amount of liters in each pool: 1,530
