How far do smells travel?

If we assume that the average mass of air (since it is a mixture of different gases) is 28.9 g/mol (or each gas particle is around 4.799*10-26), and room- temperature is 27C or 300K, we find that the average velocity of a single air particle is around 500 meter/sec or 1800 km per hour.
