Measurement of Energy Changes: Calorimetry

Heat energy is supplied at a constant rate to $400\mathrm{g}$ of ice at $0^{\mathrm{o}}\mathrm{C}$. the ice is converted into water at $0^{\mathrm{o}}\mathrm{C}$ in $5$minutes. How much time will be required to raise the temperature of water from $0^{\mathrm{o}}\mathrm{C}$ to ${100}^{\mathrm{o}}\mathrm{C}$?

 Specific latent heat of ice = 336 J g^-1, specific heat capacity of water = 4.2 J g^-1K^-1.
