A large water tank initially contains 800 gallons of water. Water is drained from the tank at a constant rate of 25 gallons per minute. The amount of water remaining in the tank, $W (t)$ , in gallons, after $t$ minutes, can be represented by the function $W (t) = 800 - 25 t$ . How many minutes will it take for the tank to be completely empty?
