Two friends, Jack and Jill, sit down to talk and enjoy a cup of coffee. When the coffee is served, Jack immediately adds a tablespoon of cream to his coffee. Jill, occupied with the discussion, waits 10 minutes before adding a tablespoon of cream, which has been kept at a constant temperature. The two friends then begin to drink their coffee. Who has the hotter coffee at that time? Assume that the cream is cooler than the air and justify your answer using Newton’s law of cooling. Please help solve this problem! Thank you!
