A water heater is operated by solar power. If the solar collector has an area of $6.00 \mathrm{~m}^{2}$ and the intensity delivered by sunlight is $550 \mathrm{~W} / \mathrm{m}^{2}$, how long does it take to increase the temperature of $1.00 \mathrm{~m}^{3}$ of water from $20.0^{\circ} \mathrm{C}$ :
to $60.0^{\circ} \mathrm{C}^{2}$
