Answer:

Image distance = 60 cm

Explanation:

Object distance from a convex lens = 20 cm

Focal length of convex lens = 15 cm

Use the following relation between the object distance, focal length and image distance.

\frac{1}{object\,\,distance}+\frac{1}{image\,\,distance}  =\frac{1}{focal\,\,length}

\frac{1}{20}+\frac{1}{image\,\,distance}=\frac{1}{15}\\\\ \frac{1}{image\,\,distance}=  \frac{1}{15}-\frac{1}{20}\\\\ \frac{1}{image\,\,distance}=  \frac{4-3}{60}   \\\\ \frac{1}{image\,\,distance}=\frac{1}{60}

Therefore,

Image distance = 60 cm
