30 Bordering Country Pairs Relatively Further Away by Geographical Center
Can you find the pairs of bordering countries that are relatively further away? Distance is measured between their geographical centers and is then divided by R1 and R2 which are the radii of circles having the same area as the two countries
Data from Portland State University (https://www.pdx.edu/econ/country-geography-data), for missing countries from CIA (https://www.cia.gov/library/publications/the-world-factbook/fields/2011.html)
Country A comes before Country B in alphabetical order; overseas borders not considered
The row highlighted in yellow is a disputed border
Hint: look for borders at the tip of 'long' countries or at countries with islands that make their centers spread away
