It depends on the person but after somewhere around 4-5 mins. the brain begins to die.
15 minutes you will die. 11 minutes will cause permanent brain damage. 8 minutes will cause brain damage
That cannot be calculated without knowing the average speed over that distance.
And have him survive? Without air, about three minutes. If they had air but not water they would die of dehydration after about three days. If they had water but not food then they would last a few weeks. If they had their needs taken care of then the average human lifespan is around 79 years.
A person can live minutes without air.
It will vary from person to person depending on how long they can hold their breath but about 3 minutes is considered the average from what I have always been told.
0 hours. The average person can only live about 2 minutes without air.
The average human normally takes in about 35 lbs of air per day.
Indefinitely.
That isn't humanly possible. 40 minutes and that guy would be LONG dead. Humans really can't last that long without air, maybe barely 5 minutes, probably less. Even so the average human would suffer brain damage after a few minutes.
'Bout 4 minutes
5 minutes
An average human breathes about 12 to 20 times per minute, depending on activity level and health. If we consider an average tidal volume (the amount of air inhaled or exhaled in a single breath) of about 500 milliliters, a person can breathe approximately 6 to 12 liters of air per minute. Therefore, in one hour, an average person breathes around 360 to 720 liters of air.
On average, a human breathes in around 12-18 times per minute. Each breath takes in about 0.5 liters of air, so in one minute a human breathes in around 6-9 liters of air.
