Two litres of water (density = $1 \mathrm{g} {\mathrm{mL}}^{-1}$) in an open lid insulated kettle is heated by an electric heater of power $1 \mathrm{kW}$. The heat is lost from the lid at the rate of $160 \mathrm{J} {\mathrm{s}}^{-1}$. The time taken for heating water (Specific heat capacity$4.2 \mathrm{kJ} {\mathrm{K}}^{-1} {\mathrm{kg}}^{-1}$) from ${20}^{\mathrm{o}}\mathrm{C}$to ${75}^{\mathrm{o}}\mathrm{C}$ is
