Homework Help: physics

Posted by Daniel on Saturday, March 17, 2012 at 11:37pm.

A convex mirror in an amusement park has a radius of curvature of 3.00m. A man stands in front of the mirror so that his image is half as tall as his actual height. At what distance must the man focus his eyes in order to see his image?

I calculated the focal length using f=(-.5)(3.00m)

then I tried to find the image distance(di) but I get stuck.

What am I supposed to be doing here?
