Answer:
a mile
A foot is usually considered .3048 of a meter. The origin of the term and of the precise length is assumed to be that a human foot was frequently used as a standard for measuring. However, the need arose for a consistent length so that "a foot" didn't mean different lengths for different people. Of course, anyone with common sense will quickly argue that most human feet are not 12 inches long. The assumption is that the 12 inches was decided upon after measuring the length of a man's foot with a shoe on it. After all, most people, when measuring with their feet, do so with shod feet. Who takes off his or her shoes to walk heel-toe when measuring?
