Why is my VBA (Visual Boy Advance) emulator running so fast?

For anyone who plays games on their computer using the emulator VBA
My emulator shows that it's running at 2000% or faster than normal speed. How do I get it lower? I've tried looking online and I can't find anything that works. I can't find a way to get it slower, I don't need it to be at 100%, just at a manageable speed. As it is now 2000% means that I can only move in straight lines, and I only stop when crashing into a wall.
