Today's Daily Brain Teaser (Dec 22, 2013)

Equidistant?



Sam and Lisa live in a city in Nevada, USA, whose streets run perfectly north-to-south and east-to-west. They are at the intersection of Harrison Street, which is north-south, and Jefferson Street, which is east-west. They are both walking to an intersection that is a few blocks east and a few blocks south from where they are now. They both take direct routes, using only two streets each (and therefore making only one turn each), but Sam takes Harrison Street while Lisa takes Jefferson Street. Assuming that neither encounters any obstacles, and that the turns take the same distance to complete, is there any reason why Sam's path or Lisa's path could be considered longer than the other's?
