Question

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?

Answer 1

The rate at which tea is poured in the cafeteria is,
4 cups / minute
There are 120 minutes in 2 hours. Thus, the number of cups poured is,
(4 cups / minute) x (120 minute) = 480 cups
Each gallon is made up of 16 cups. Thus, 480 cups is also equal to 30.
