On Monday, water was pumped out of the pool at a constant rate, starting at 12:00 p. m. At 12:15 p. m., the water in the pool was 45 inches deep.

At 12:35 p. m., the water in the pool was 41 inches deep.

Part A - By how many inches does the depth of the water decrease each minute?

Every ten minutes the water decreases by two, so you would divide 2/10, which would be 0.2, meaning the water decreases 0.2 inches per minute.

so every 20 minutes it goes down by 4 inches so 20x-4y

Step-by-step explanation:

20x-4y means every 20 minutes it goes down 4 inches
