Final answer:
To find the rate at which the water is leaking from the container, subtract the final amount from the initial amount and divide by the time interval.
Step-by-step explanation:
To find the rate at which the water is leaking, we need to determine how much water is being lost per minute. We can do this by finding the difference in the amount of water at two different times and dividing it by the time interval:
Amount of water lost = Initial amount of water - Final amount of water
Rate of leakage = Amount of water lost / Time interval
We know that the initial amount of water is 8 gallons and the final amount is 3 gallons. The time interval is given as 40 minutes. Therefore, the rate of leakage is:
Rate of leakage = (8 - 3) gallons / 40 minutes = 5 gallons / 40 minutes
Since we need the rate in gallon/minute, we can simplify the fraction:
Rate of leakage = 5/40 gallons/minute
Therefore, the water is leaking at a rate of 5/40 gallons per minute.
