Me: Brother, I think if there is a running competition, people will definitely outrun dogs.
brother: why
Me: Because dogs have four legs, people only have two
Brother: Do you run faster if you have more legs? What theory is this, what about spiders?
Me: uh ⊙∀⊙!
Brother: Where's the centipede?
Me: uh ⊙∀⊙! Because spiders have short legs
Brother: That man is tall
Um ⊙ Then what is the factor related to running fast? The length of the legs, the number of legs, the number of muscles. .
What is the ratio?
