The 2004 Olympic gold medalist in the 100 meter dash was Justin Gatlin of the United States in a time of 9.85 seconds.
For a 17 year old boy, the average 400m is anywhere from 54-51 seconds. For a 17 year old girl, there really is no average time because an individual's time can fluctuate anywhere from 73-59 seconds. It pretty much depends on your body type and how experienced you are with the race. Hope that helps :)
