Hi, my name is Dr. Stephens and this is a question that I frequently get asked. According to scientific research, air is measured in yorths; given by the scientist Dwayne Yorths. Depending on the force of the yawn, there is a probability that a single yawn can travel up to 3000 yorths/fn
This might not make much sense to you due to the fact that this is a improvised, made up answer.
Thanks for wasting your time.
Dr. Stephens
It is fast, Jacob....
As fast as the prevailing wind. 25-30mph.
People yawn because the body reacks to oragans and air gets traped
it can travel through the air at about 300 mph
You yawn when you are sleepy because that is when you take in the least oxygen. Your body takes in more oxygen when you are yawning, which explains the reason to why you take in air when you yawn.
Because when you get sleepy your body goes into a sleep mode and takes in less air but since your awake and need more air you yawn to get 'emergency' air. Hope that helped
3oo,ooo,ooom/s
An airplane can travel at a speed of 400kmph to 9000kmph.
Maybe 100 Km per hour:o
in air sound travels 330m/s
yawns are contagious becuase when we see another person yawn our brain sees it as that person is gasping for air and they dont have enough oxygen so as a defense mechenisme we will yawn also.
Humans are not capable of running that fast, no, but they can travel that fast using a vehicle. The current air speed record is Mach 6.7.
