Question

The sun shines on a $150-\mathrm{m}^{2}$ road surface so that it is at $45^{\circ} \mathrm{C}$. Below the 5 -cm-thick asphalt, with average conductivity of $0.06 \mathrm{W} / \mathrm{m} \mathrm{K},$ is a layer of compacted nubble at a temperature of $15^{\circ} \mathrm{C}$. Find the rate of heat transfer to the rubble.
