Calculation of the Time Difference between Meridians

To calculate the time difference between two meridians, we need to consider that the Earth is divided into 24 time zones, each spanning 15 degrees of longitude. The standard time for each time zone is based on the Prime Meridian, which passes through Greenwich, London, and is assigned a longitude of 0 degrees.

To calculate the time difference between two meridians, we can use the following formula:

Time Difference = (Longitude2 - Longitude1) * 4 minutes

Let's calculate the time differences for the given meridians:

a) 30° east of the Prime Meridian (1-45° east of the Prime Meridian): - Longitude2: 30° east - Longitude1: 1-45° east

Applying the formula: Time Difference = (30 - (-45)) * 4 minutes Time Difference = 75 * 4 minutes Time Difference = 300 minutes

Therefore, the time difference between these two meridians is 300 minutes.

b) 30° west of the Prime Meridian and 10° east of the Prime Meridian: - Longitude2: 30° west - Longitude1: 10° east

Applying the formula: Time Difference = (30 - 10) * 4 minutes Time Difference = 20 * 4 minutes Time Difference = 80 minutes

Therefore, the time difference between these two meridians is 80 minutes.

Please note that the time difference calculated above is based on the assumption that each time zone spans 15 degrees of longitude and that the time difference between adjacent time zones is 1 hour (60 minutes). However, it's important to consider that some countries or regions may have adopted different time offsets due to political or geographical reasons.
