At the rectangular intersection of two streets, the crosswalks are 60 feet from north to south, and 80 feet from west to east. If a diagonal crosswalk was installed, how many fewer feet would a person have to walk to get from the NW corner to the SE corner?

you should recognize a scaled-up 3-4-5 right triangle. So, the diagonal is 100 ft.

The rest is a cinch, right?
