Sketch the situation if necessary and use related rates to solve. A 5 ft tall person walks toward a wall at a rate of 4 ft/s. A spotlight is located on the ground 40 ft from the wall. How fast (in ft/s) does the height of the person's shadow on the wall change when the person is 10 ft from the wall? ft/s What is the rate (in ft/s) at which the shadow changes when the person is 10 ft from the wall, if the person is walking away from the wall at a rate of 4 ft/s? ft/s
