At what average rate did the bathtub fill with water?

1 answer

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.
