Answer:
2nd tank
Step-by-step explanation:
The rate of filling, in gallons per minute, is found by dividing gallons by minutes.
Tank 1
(3/4 gal)/(2/3 min) = (3/4)(3/2) gal/min = 9/8 gal/min
Tank 2
(5/8 gal)/(1/2 min) = (5/8)(2/1) gal/min = 10/8 gal/min
10/8 gal/min is more than 9/8 gal/minute.
The second tank is filling faster.
