One day, Rabbit was about to go for a meeting with Donkey, but Winnie the Pooh and Duck unexpectedly came to his home. Being well-bred, Rabbit offered the guests some refreshments. Pooh tied Duck’s mouth by a napkin and ate

5

3

minutes for a cup of milk, he computed the time the guests would have needed to devastate his supplies. What is that time?
