Answer:
<em>The water is leaking at the rate of 0.0625 gal/min.</em>
Step-by-step explanation:
<u>Rate of change</u>
The rate of change (ROC) is a measure that compares two quantities, usually to know how fast one variable changes in time.
The container holds 8 gallons of water and is leaking at a constant rate to be calculated later.
When 48 minutes have passed, the container has 5 gallons of water left. This means it has leaked 8 gallons - 5 gallons = 3 gallons.
Calculating the rate at which it's leaking:

r = 0.0625 gal/min
The water is leaking at the rate of 0.0625 gal/min.
64899.4
Explanation: rounding to the nearest ten is the first number AFTER the decimal. You round up one of the 2nd number is greater than 5, but it is 4 in this case. The answer would be 64899.4
