Let's figure out how many cups are in 12.5 quarts first. There are 2 cups to a pint and 2 pints to a quart, so figure 4 cups per quart. 12.5 x 4 = 50. If you add the 3 cups of lemon juice to this number, then you get 53 total cups of liquid used to make Justin's lemonade.
assuming the cup is 250ml (average) about 0.5
53 quarts = 212 cups
53 fluid ounces is 6.625 cups. (US)
That is 106 cups
424 pints is 53 gallons.
212 two cups=one pint two pints=one quart=four cups (4 cups/quart)(53 quarts)=212 cups
53/4 gallons is 23 quarts.
53
(53 cups) / (4 cups per quart) = 13.25 quarts
12,240 cubic inches equates to about 53 (52.987013) US gallons.
85-53=32--->..... 32 divided by 8 = ..... 4 gallons per minute.
