The owner of a van installs a rear-window lens that has a focal length of -0.295 m. When the owner looks out during the lens at a person standing directly behind the van, the person appears to be now 0.242 m from the back of the van, and appears to be 0.339 m tall.

1. How far from the van is the person really standing?

 

2. How tall is the person?
