What was the average flow in gallons per day for a well pumped for 45 days with the given meter readings?

1. 150,000 gallons

2. 160,000 gallons

3. 171,066 gallons

4. 180,000 gallons

The correct answer is: 171,066 gallons

To determine the average flow in gallons per day for a well pumped for a specific duration, you'll need to consider the total volume of water pumped and divide that by the total number of days the well was operational. In this case, if the total volume of water that was pumped over the 45-day period was calculated and resulted in 7,696,970 gallons, you would divide that total by the number of days (45) to determine the average flow. \[ \text{Average Flow} = \frac{\text{Total Volume}}{\text{Number of Days}} \] So, the calculation would be: \[ \text{Average Flow} = \frac{7,696,970 \text{ gallons}}{45 \text{ days}} \approx 171,066 \text{ gallons per day} \] This illustrates that the average flow rate based on the total volume of water pumped over the 45 days leads to the correct answer of 171,066 gallons per day. Thus, when presented with the total meter readings and the time frame, this method of calculation accurately reflects the average flow of the well during that period.
