GENERAL KNOWLEDGE

Detailed explanation-1: -Each degree of longitude has a time difference of 4 minutes. So, if it’s 12 o’clock in Greenwich (0 degrees), it’s 12:04 o’clock in 1 degree meridian, and so on. Q. For every degree of longitude the time difference is four minutes.

Detailed explanation-2: -One degree of latitude equals approximately 364, 000 feet (69 miles), one minute equals 6, 068 feet (1.15 miles), and one-second equals 101 feet.

Detailed explanation-3: -Detailed Solution. The correct answer is 4 seconds. Longitude is usually measured in degrees, minutes, and seconds, and 4 seconds time differences occur for every 1-minute longitudinal difference. 15 minutes of longitude = 1 minute difference; 1 minute of longitude = 4 seconds difference.
