A 5.5-foot-tall woman walks at 4 ft/s toward a street light that is 33 ft above the ground. What is the rate of change of the length of her shadow when she is 20 ft from the street light? At what rate is the tip of her shadow moving? Let L be the length of the woman's shadow and let x be the woman's distance from the street light. Write an equation that relates L and x.
