If the standard time is of a country is GMT + 1hr, which longitude's local time is adopted by the country?

60°W

60°E

16°W

15°E Correct answer

Answer Details

If the standard time of a country is GMT + 1hr, it means that the country is one hour ahead of the Greenwich Mean Time, which is the reference time for the world. Since each degree of longitude is equivalent to four minutes of time difference, the country is located 15 degrees east of the Prime Meridian (0 degrees longitude), which is the reference line for longitude. Therefore, the longitude's local time adopted by the country is 15°E.
