Hello! So you know how the world is a big round ball, right? Well, to help people find their way around it, we have imaginary lines drawn all over it called meridians.
The 11th meridian east is one of those imaginary lines. It's like a big circle that goes from the North Pole all the way down to the South Pole, and it's 11 meridians away from the one right in the middle, called the Prime Meridian.
The 11th meridian east goes through a few different countries, like Germany, Switzerland, Italy, Libya, and even Antarctica! It's important because it helps people navigate, like when they're using a map or a GPS to find their way around.
So next time you look at a map of the world, try to find the 11th meridian east and see what countries it goes through!
