Change of State

Water and ice having equal masses are placed inside an insulated container. The initial temperatures of water and ice are $40°\mathrm{C}$ and $0°\mathrm{C}$ respectively. The equilibrium temperature of the system in degrees Celsius is close to (Note: take the specific heat of water $=4000 \mathrm{J}·{\mathrm{kg}}^{-1}·{\mathrm{K}}^{-1}$; latent heat of fusion $=300 \mathrm{kJ}·{\mathrm{kg}}^{-1}$ )
