A block of ice at a temperature of 0 ∘C0\ ^\circ\text{C}0 ∘C is placed into a glass of warm juice at a temperature of 15 ∘C15\ ^\circ\text{C}15 ∘C.
After a short time, some of the ice has melted and the juice has cooled to a temperature of 11 ∘C11\ ^\circ\text{C}11 ∘C.
What is the temperature of the remaining ice?
