during A catered lunch an average of 4 cups of tea are poured per minute. The lunch will last two hours. How many gallons of tea should the caterer bring if there are 16 cups in 1 gallon

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
