About 12 inches each year.
The average miles driven per person each year in New York is 15,000 miles. The average number of miles a taxi driver drives in a 12 hour period is 180.

I would say that the average 12-year-old weighs about 35-45 kilograms, although it varies from the person's height.
I have read that the average person eats about 12 spiders per year in their sleep.
The average person's hair grows approximately 1/2 inch each month. 12 months= 6 inches.
the average maid made atleast 12 tuppences a year and the average man made 18 tuppences a year
Add together the total sales for each month of the year. Divided this total by 12 to find the average.

12 i think
Imagine 12 results for average rainfall each month, then the average of all the months combined would give the average rainfall during that year.
On average about 12 hours, but it can be anywhere from 0 to 24 hours, depending on your latitude and the time of the year.
