An odd question, I know. I've scoured the internet and can't seem to get an answer, so I am asking here. For reasons I don't feel the need to disclose due to it being unimportant, I am trying to calculate how many blocks per second an experience orb travels on average. I've noticed that experience orbs pick up speed as they get closer to the player, but I'm asking for either a calculated median speed between the slowest and fastest speed, or both the slowest and fastest speed an orb of experience can go. I'm asking for both editions, so if the speed is different between them, mark what edition the speed is for.
In conclusion, what is the average blocks per second that an orb of experience travels?
