Detailed explanation-1: -As Earth rotates on its axis, it moves about 15 degrees every 60 minutes. After 24 hours, it has completed a full rotation of 360 degrees. The scientists used this information to divide the planet into 24 sections or time zones. Each time zone is 15 degrees of longitude wide.
Detailed explanation-2: -As a result of this scientists divided the Earth into 24 different sections known as time zones. Each time zone is 15 degrees of longitude wide. The starting point for these time zones is the prime meridian in Greenwich, also called Greenwich Mean Time (GMT).
Detailed explanation-3: -There are 24 hours in a day, and 360 degrees of longitude encompassing the globe – dividing 360 by 24 gives you the 15 degrees of longitude that equates to a one-hour difference in each time zone.
Detailed explanation-4: -Answers: 360 degrees ÷ 24 hours = 15 degrees per hour. Each time zone covers 15 degrees of longitude.
