I think anything under 30 seconds is pretty good.
The fastest growing group of people filing for bankruptcy are those under the age of 25.
Most likely 18 seconds or slower.
27 seconds is a great time for a 50 freestyle. your time also depends on wether your a competitive swimmer or not if you are not you should be! dats a pretty good time! check usaswimming.com for the a, aa, aaa, aaaa times if your a competitive swima!
25 minutes and 57 seconds
speed = distance/time
My son is 9.5 years old and does 21.5 seconds, he is pretty good at his class
Lornah Kiplagat in 1h06:25 is the fastest recognised record (unassisted course)
The Time Magazine Person of the Year in 1966 was Twenty-Five and Under 25.
There are no 25 yard events event at the international level. Typically only very young swimmers (12 years and under) swim 25 yard events. However, given that the world record for the 50 yard freestyle is 18.47 (set by Cesar Cielo at the 2008 NCAA Championships), I would guess that the fastest 25 yard free ever swum would be 9.0 seconds or faster.
my fastest time is (im eleven) 25 mins and 22 secs. but the average time(for an adult) is between 30-40 mins. :)
A good time depends on a lot of different things. Like how long the event is and how old you are. If you are thinking of only a 50 yard freestyle (down and back in 25 yard pool) a good time for a high school swimmer would be between 23 seconds-25 seconds. A great time is between 20 seconds- 22 seconds. If you are a college swimmer however a good time would be about 20-21 and a great time is around 18-20 (phelps does around a 16-17)
