Answer:
You don't give any context it's kinda vague but it's speed so I'll given. I'll give you examples that you can clearly see a speed choices change
1. A snail: This is an organism that is slow going at 0.03 mph
2. A human: The fastest human ever recorded is Olympic Legend Usian Bolt going at 27.63 mph
3. A cheetah: A cheetah can reach speeds up to 80 mph
Now just in case this isn't what you need and it types of speed you got that for 1, for 2 you could say internet speed referring to the electronic side, and for a 3rd the earth for a solar reference. If this is still not it then the last thing is
1. Uniform Speed
2. Average Speed
3. Instantaneous Speed
if a 4th is need 4. Variable Speed
I hope this helps
