Convert 7qt/min into gallons per hour

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

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
