(1 point) The illumination of an object by a light source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. If two light sources, one 8 times as strong as the other, are placed 4 ft apart, how many feet from the brighter source should an object be placed on the line between the sources so as to receive the least illumination? ft
