Let the distance of the person from the object be = D meters

Distance of image from mirror = D + 1  meters

The triangle made by image of object, at the eyes and triangle made by mirror at the eyes have the same angle of elevation.

Distance of the image from the eyes = D + 2 meters

Hence  15 / 0.20 = (D+2) / 1   

      Solving it  D = 73 meters
