(17%) Problem 5: An object is placed in front of a lens with a focal length of ( 29.7 mathrm{~cm} ). With its initial placement, an inverted image that is 2.99 times the size of the object is produced. The position of the object is changed, and now an upright image that is 1.61 times the size of the object is produced. What distance, in centimeters, was the object moved?
