Question

What is the farthest a person can smell something like how many feet away?

Answer 1

Some substances have such a pungent odour that you can smell one part per trillion, and some moths have a more acute sense of smell than us, which they use to find mates.  In some cases a male can sense a female 3 km. away.

Answer 2

The odor of heavy smoke, for instance, can be detected many miles away. Most memorably, the smoke from the World Trade Center on 9/11 was both visible and smellable where I live, 30 miles away.

Answer 3

it is really up to the person, but why dont you cook something and find out yourself...

Answer 4

20 feet

Answer 5

It depends on what it is.  Some smells just permeate an entire region.  Like a town with a lot of livestock smells like c**p.  The entire town of Gilroy, CA, smells like garlic because they grow so much of it.   You can smell a fire from a long, long way off.
