Final answer:
The pond loses water at a rate of 1 gallon per hour. Over 11 hours, it will lose 11 gallons of water.
Step-by-step explanation:
The question involves calculating the rate of water loss in a pond and then applying that rate to find out how much water would be lost over a different amount of time. If the pond loses 16 gallons of water in 16 hours, we can find the rate of loss per hour by dividing the total loss by the number of hours, which gives us:
Rate of loss = 16 gallons / 16 hours = 1 gallon/hour.
Now, we can use this rate to calculate the loss for 11 hours:
Water loss in 11 hours = Rate of loss × Number of hours = 1 gallon/hour × 11 hours = 11 gallons.
Therefore, the pond will lose 11.0 gallons of water in 11 hours, which corresponds to answer choice (a).
