I don't know but upon reading, this might give you a hint. "The North Star is visible every night in about the same place."
 
Sorry I didn't get your hint . Could you elaborate your response .
 
The Earth rotates... When does the green man see the star rising, later or sooner than the blue man does?

OK .

20° longitude difference = 80 minutes

Option d)

Right ?

I hope so. Supposing there are no big building or hills hiding the raising sun :)
