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

There are 16 cups in a gallon. Which means that every 4 minutes, a gallon of tea is being poured. In an hour there is 60 minutes, so in an hour 15 gallons are being poured. Multiply that by 2 for the 2 hours the lunch will last and 30 gallons are going to be poured.

Answer: 30 gallons

Answer 2

The caterer should bring 30 gallons of tea.

Explanation:

During a catered lunch, an average of 4 cups of tea are poured per minute.

The lunch will last 2 hours.

1 hour = 60 minutes

2 hours = 60 × 2 = 120 minutes

in 120 minutes tea are poured = 4 × 120 = 480 cups

There are 16 cups = 1 gallon

480 cups =
`(480)/(16)`

= 30 gallons

The caterer should bring 30 gallons of tea.
