To determine when the 50-gallon hot water tank will run out of hot water when using water at a rate of 1.2 gallons per minute, you can calculate the time as follows:
- Start with the total volume of the tank: 50 gallons.
- Divide the volume by the rate of water usage:
\[ \text{Time} = \frac{\text{Total Volume}}{\text{Rate of Usage}} = \frac{50 \text{ gallons}}{1.2 \text{ gallons/minute}} \approx 41.67 \text{ minutes} \]
Since the tank will run out of hot water in approximately 41.67 minutes, you can conclude:
- It will run out of water in approximately 41.67 minutes.
- Therefore, 50 minutes is not a viable option, as it is longer than the time the tank can supply hot water.
The correct response is: It will run out of water in 41.666666 minutes. No, 50 is not a viable option.
