Resistance of metal placed in water

The resistance of metal wire is 25 ohms when it is placed in melting ice and 80 ohms when placed in boiling water. What is its resistance when the metal wire is placed in water at 80 degree Celsius? Assume the resistance of the metal with increases linesrly with temperature.
