Step-by-step explanation:
To answer this question, we need to know that the Earth is divided into 24 time zones, with each time zone covering 15 degrees of longitude. The time at the Greenwich Meridian (0 degrees) is known as Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC), and each time zone is one hour ahead or behind of the adjacent time zone.
Therefore, if it is 11 a.m. at 45 degrees east, we know that it is 3 hours ahead of GMT (since 45 degrees east is 3 time zones ahead of GMT, which is at 0 degrees).
To find out the time at 60 degrees east, we need to determine how many additional time zones there are between 45 degrees east and 60 degrees east. Since each time zone covers 15 degrees of longitude, we can calculate the difference in longitude between 45 degrees east and 60 degrees east:
60 degrees east - 45 degrees east = 15 degrees
So, 60 degrees east is one additional time zone ahead of 45 degrees east, making it 4 hours ahead of GMT.
Therefore, if it is 11 a.m. at 45 degrees east, it would be 3 p.m. at 60 degrees east (since it is 4 hours ahead of GMT).
