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

30 gallons 

4*60=240
240*2=480
480/16=30

Answer 2

2 Hours is 120 minutes. 4 cups per minute is 120×4. 120×4=480 cups. 480÷16 is the amount of gallons. 480÷16 is 30. 30 gallons of tea should be brought.
