Question 1607Navigation General

The correct answer is D) 157°30'E. The dividing meridian between time zone descriptions -10 and -11 is 157°30'E, as defined in the International Date Line and Time Zone Regulations. This line separates the time zones used in the western Pacific Ocean, with -10 representing Hawaii-Aleutian Time and -11 representing Samoa Time. The other options are incorrect because they represent different meridians that do not correspond to the boundary between the -10 and -11 time zones.
