The answer is 30.
There are 16 cups in a gallon. And 120 minutes in 2 hours. so multiple
16*120 which is 480. Then divide 480/120 and get 30 as your answer

we know that

An average of
4 cups of tea are poured per minute

Step 1

Find the number of cups that are poured in two hours by proportion

Remember that


2\ hours=120\ minutes


(4)/(1) (cups)/(minute) =(x)/(120)(cups)/(minutes) \\ \\x=120*4 \\ \\x=480\ cups

Step 2

Convert cups to gallons by proportion

Remember that


16\ cups=1\ gallon


(1)/(16) (gallon)/(cups) =(x)/(480) (gallons)/(cups) \\ \\x=480/16 \\ \\x=30\ gallons

therefore

the answer is


30\ gallons
