KNOWNS:
Diverging (convex) mirror
Radius of curvature = 60 cm
(f = 30 cm)
M = 1/5
Hi = 20 cm
UNKNOWNS:
Ho?
Di?
Do?
EQUATIONS:
1/Do + 1/Di = 1/f
M = Hi/Ho = -Di/Do

I got:
Ho=100 cm
Di=-24 cm
Do=120 cm
I rearranged -Di/Do=1/5 to get -5Di=Do.
Then I substituted -5Di in for Do in 1/Do + 1/Di = 1/30 to solve for Di. Is that right?

I doubt if it is right because you should be using -30 for the focal length, since it is a convex mirror.
