Alright kiddo, so the 113th meridian west is a very big imaginary line that goes from the North Pole all the way down to the South Pole. It's like a special map line that helps us know where we are in the world.
Think about a playground with a big circle in the middle. The circle is like the Earth and the 113th meridian is like a line that goes right through the middle of that circle. If you stand on one side of that line and your friend stands on the other, you're both on different sides of the world!
But why is this line important? Well, it helps us know where different countries are located. For example, if you look at a map and see that the 113th meridian goes through Mexico and the United States, you know that those two countries are on opposite sides of that imaginary line.
It also helps us know what time it is in different parts of the world. If you live on the east side of the 113th meridian, your time zone might be different than someone who lives on the west side of the line.
So, that's the 113th meridian west - a big imaginary line that helps us know where we are in the world and what time it is in different parts of the world!
