Alright kiddo, imagine a very long line that goes all the way around the Earth. This line is called the Prime Meridian and it helps us measure where things are on our planet.
Now, imagine another line that runs parallel to the Prime Meridian but is 115 degrees to the east of it, and this line is called the 115th meridian east. This line helps us pinpoint specific places even more precisely, by dividing the Earth into smaller sections.
So, if you were standing on the 115th meridian east, you would be standing on a very long line that runs from the North Pole to the South Pole. Places that are east of this line would have a longitude value of, you guessed it, more than 115 degrees east. And places that are west of this line would have a longitude value of less than 115 degrees east.
This specific meridian is important because it passes through many countries like Australia, Indonesia, and China, and helps people navigate and communicate more accurately about specific locations within those countries.
