The object is situated #27.32# centimeters from the center of the mirror.

Explanation:

We must use the Mirror Equation, which states that

#1/f = 1/x_1+1/x_2#

Where #f# is the focal lengh, #x_1# is the distance from the object to the mirror and #x_2# is the distance from the image to the mirror. We have to find #x_1#:

#1/x_1 = 1/f - 1/x_2#

#1/x_1 = 1/16-1/38.6 = =0.0366#

#:. x_1 = 1/0.0366 = 27.32 " cm"#
