We know that 1 gallon= 4 quarts therefore, 14 gallons=56 quarts so 14gallons/s=56 qt/s
if we would need to find just gallons/second in quarts /second the answer will be simple, but we need to find the answer in qt/min is there are 56 qt per second, it means that it will be 56*60 in 1 minute 56*60=3360 final answer 14 gallons/s=3360 qt/min
