A platinum wire is used to determine the melting point of

A platinum wire is used to determine the melting point of indium.The resistance of the platinum wire is 2.000 Ω at 20 degrees Celsius and increasesto 3.072 Ω as indium starts to melt. What is the melting point of indium? (The temperature coefficient of resistivity for platinumis 3.9 x 10^-3/ degrees celisus.)
