If it is 4pm at 15 degrees W, what time is it at 30degrees E?
To determine the time at 30 degrees E, we need to consider the concept of time zones and the rotation of the Earth.
The Earth is divided into 24 time zones, each spanning 15 degrees of longitude. The time at any given location is generally based on the time zone it falls in. Moving from west to east, each time zone is one hour ahead of the previous one.
In this case, if it is 4 pm at 15 degrees W, we know that the location is already in a time zone 15 degrees behind Greenwich Mean Time (GMT), which serves as a reference point.
To find the time at 30 degrees E, we need to calculate the time difference between 15 degrees W and 30 degrees E. Since each time zone covers 15 degrees of longitude, 30 degrees E is two time zones ahead of Greenwich Mean Time (GMT).
Therefore, the time at 30 degrees E would be two hours ahead of the time at 15 degrees W. So if it is 4 pm at 15 degrees W, it would be 6 pm at 30 degrees E.
