At what average rate did the bathtub fill with water?

To find the average rate at which the bathtub filled with water, we need to determine the change in the amount of water over a given time period.

From the table, we can see that the amount of water increased by 3 gallons every 2 minutes.

Therefore, the average rate at which the bathtub filled with water is 3 gallons per 2 minutes, or 1.5 gallons per minute.
