The owner of a van installs a rear-window lens that has a focal length of -0.300 m. when the owner looks out during the lens at a person standing directly behind the van, the person appears to be just 0.240 m from the back of the van, am appears to be 0.34 m tall.

a) How far from the van is the person actually standing, and

b) How tall is the person?
