Further Investigations

Can you come up with an equation that could help someone else accurately predict the final temperature for 3 different volumes of water mixing, while only knowing the initial temperatures and volumes?

You have a bathtub that has 60 liters of 30 degrees Celsius water in it and you want to bring the temperature up to 40 degrees Celsius. What is the least number of readings you can make with the temperature sensor to get your desired final temperature? Note: you can try this with a bathtub at home, or do it on a smaller scale using cups of water in the classroom.
