Which of these cities is furthest west?

Your answer is correct. However, Pittsburgh is not west of Warren! Your numbers are not correct! Warren is 80.818 W & Pittsburgh is 79.995 W.

Yeah that got me, I thought for sure it was Warren, Ohio.

You cannot draw a straight line and expect to get the proper results. Lines of longitude are not parallel. They converge at the poles.You must look at a map with lines of longitude or look up the coordinates for each city to understand how this works. Do not use the coordinates provided in this answer. They are wrong and put Pittsburgh, PA farther west than Warren, OH, which, of course, is impossible.

Guillermo J Garzon , It’s not “sense” which makes measurement.

How in US Jacksonville,Fl is farthest west if is located in the east. Doesn’t make any sense at all.

Vince Duncan. Me too. Jacksonville Beach.

Missed it. And I live in Jacksonville, FL. D’oh!

No clue

The answers for Warren, OH and Pittsburgh, PA are mixed up. Warren is farther west.

Live in Ohio...knew it was between Warren and Jacksonville, then figured it was a trick question

Different question, got it

Answered incorrectly. These questions are not making sense. Wrong explanations.

Here is another one, LA is further east than Reno.

Huh Jacksonville, Florida that's where i was born there.

I guess the trick here is to look at a globe verses a flat map

Guessed wrong

Just think of a map of the US East Coast. Florida coast turns eastward.

Yes, very tricky!
