1. The problem statement, all variables and given/known data

A concave mirror has a focal length of f=50 cm. If an object is at o=500cm, where is the image?

2. Relevant equations

1/f = 1/o + 1/i

3. The attempt at a solution

1/50 = 1/500 + 1/55.56

What I don't understand is "where is the image"? How do I interpret it from my solution?

You have found the value of 1/i =1/55.56 therefore i=55.56 in other words the image is 55.56 cm from the mirror.
