we first need to turn every thing into the same unit of measure ment

1 gallon=4 quarts
60 minutes=1hour

7*60=420  420 is how many quarts per hour but we want gallons so we want to divide by 4
420/4=105
105 gallons per hour
apologiabiology
so
qt=quart
4 quart=1 gallon
1 quart=1/4 gallon
min=minute
60 minutes in 1 hour
1 minute=1/60 hour

so 7 quarts=7 times 1/4 gallons=7/4 gallons
1 minute=1 times 1/60 hours=1/60 minutes

7/4 gallons per 1/60 minutes
(7/4gal)/(1/60h)
we don't really need to divide so multiply the whole thing by (1/60)/(1/60) to clear bottom fraction
(7/4 times 60/1)/(1/60 times 60/1)=(420/4)/(60/60)=(420/4)/(1) =420/4=210/2=105/1=105 gallons per hour

the asnwer is 105 gallons per hour
