Explanation:
See picture
When the amount of carbon is plotted based on efficiency, the following graph is obtained (see image)
when looking at the graph, it can be seen that the point of lowest emission is presented with the maximum possible efficiency, 30 miles per gallon and this value is 10400 pounds per 15000 cubic miles.
