After t minutes, Tank A contains

6000 gal - (2 gal/min) t

while Tank B contains

8250 gal - (3 gal/min) t

The two tanks hold the same amount of water when these quantities are equal. Solve for t :

6000 gal - (2 gal/min) t = 8250 gal - (3 gal/min) t

(1 gal/min) t = 2250 gal

t = (2250 gal) / (1 gal/min) = 2250 min
