To find out how many weeks it will take to empty the tank, we need to divide the total volume of water in the tank by the rate at which it is leaking.
The tank contains 2520 gallons of water, and it leaks at a rate of 7 gallons per week.
We calculate the time it takes to empty the tank as follows:
\[ \text{Time (in weeks)} = \frac{\text{Total volume of water}}{\text{Leak rate}} = \frac{2520 \text{ gallons}}{7 \text{ gallons/week}} = 360 \text{ weeks} \]
Thus, it will take 360 weeks to empty the tank.
The correct answer is:
C. 360 Weeks
