Three liquids are at temperatures of 2 ◦C, 25◦C, and 30◦C, respectively. Equal masses of the first two liquids are mixed, and the equilibrium temperature is 22◦C. Equal masses of the second and third are then mixed, and the equilibrium temperature is 27.4 ◦C. Find the equilibrium temperature when equal masses of the first and third are mixed. Answer in units of ◦C.
