Explain lift-to-drag (L/D) ratio.

Explanation should include the following:

The L/D ratio is the amount of lift generated by a wing or airfoil compared to its drag.
The ratio of L/D indicates airfoil/wing efficiency.
Aircraft with higher L/D ratios are more efficient than those with lower L/D ratios.
