A landscape light at ground level lights up the side of a tall building that is 15 feet from the light. A 6-ft-tall man starts walking (on flat terrain) from the light directly toward the building. How fast is he walking when he is 9 feet from the light if his shadow on the building is shrinking at 2 ft/s at that instant?
