if the time is 1.ppm in long0degree ,what will be the time in long 20 degree E
To determine the time in longitude 20 degrees east when the time is at 1 PM in longitude 0 degrees, you need to consider the concept of time zones and the Earth's rotation.
1. First, calculate the time difference between longitude 0 degrees (also known as the Prime Meridian) and longitude 20 degrees east. Since each time zone covers 15 degrees of longitude, there is a time difference of 1 hour for every 15 degrees. Therefore, the time difference between 0 degrees and 20 degrees east is 20/15 = 1.33 hours or approximately 1 hour and 20 minutes.
2. Next, add the time difference to the given time in longitude 0 degrees. If it is 1 PM in longitude 0 degrees, adding 1 hour and 20 minutes will give you the time in longitude 20 degrees east.
Therefore, the time in longitude 20 degrees east would be approximately 2:20 PM.
