During a catered lunch, an average of 4 cups of tea are poured per minute. the lunch will last 2 hours. how many gallons of tea should the caterer bring if there are 16 cups in one gallon?

4 cups every minute means 240 cups every hour:
4 X 60 (minutes per hour)

The lunch last 2 hours so if 240 cups is every hour then 480 cups would be for 2 hours.

Now covert 480 cups to gallons.  It takes 16 cups to make 1 gallon.  We would divide 480/16 = 30 gallons
