Step-by-step explanation:
To find the rate at which water is flowing into the tank, you can set up a proportion based on the given information.
Let "R" represent the rate at which water is flowing into the tank in gallons per minute (gpm).
You know that in 25 minutes, there are 40 gallons of water in the tank. So, you can set up the following proportion:
(40 gallons) / (25 minutes) = R (gallons per minute)
Now, solve for R:
R = (40 gallons) / (25 minutes)
R = 1.6 gallons per minute
So, the rate at which water is flowing into the tank is 1.6 gallons per minute. You can represent this relationship with the equation:
R = 1.6
