Answer:
30 gallons
Step-by-step explanation:
One hour has 60 minutes, thus, two hours have 60*2 = 120 minutes.
If 4 cups are poured per minute, in 120 minutes, the number of poured cups is:
4*120 = 480 cups.
In 2 hours they pour 480 cups.
We need the answer in gallons:
Since 16 cups are equivalent to 1 gallon, we divide the 480 cups by 16 to find the number of gallons:
480/16 = 30 gallons
⇒480 cups are equivalent to 30 gallons
