First, you need to learn the equations. It's not that hard.
1/Do + 1/Di = 1/f
Do is the object distance from the mirror and Di is the distance to the image from the mirror. f is the focal length.
Use that equation to solve for Di.
1/1.6 + 1/Di = 1/0.45
1/Di = 1.597
Di = 0.6261 m
The magnification is M = Di/Do.
