For a 15 year old is 56.9secs fast in the 400m dash?

Very fast, you have the potential to go below 52 in a year with the correct regiment of training, food, muscle development and rest (including strecthing)

The world record is: 3:43.13 by Hicham El Guerrouj of Morocco.  But for 12 yrs old 7min mile is  pretty good, better than most adults.  \n\nMy best time was when I was in high school, I ran a 5min 18sec. mile.

Probably under 100pds...Depends on your height also...

That depends on your athletic ability.  Pro football players and Olympic track stars can run the 40 anywhere between 4.2 and 4.6 seconds.  Average athletes should be around 5.0-5.3 seconds.

Actually, those are pretty good times, especially for a freshman. I ran a 58 400m my sophmore year (my first year running track). The good news is, if you can run a 61/ 2.21 as a freshman, you have some pretty good natural ability. Keep training, and the seconds will start to come off. Work hard, and you could even get below 50 for the 400m by your junior or senior year. Exciting, huh?

sorry to inform  you, but one time around is only a 400 dear.  1600 (one mile) is 4 laps.\n\nJust keep working at it and you'll build the stamina over time...just keep working hard and talk to your track coach and get a recommendation from him.

90 mph. 90+30= 120 speed / 2 LAPS = 60 mph average

I think you should take about between 8 and 10 minutes for a healthy teen to run a mile, because "perfection" is about 7 minutes for a boy aged 16.

its not hard at all. a kilometer is .6 of a mile. most highschool guys run a mile around six min if they are in shape, and alot of them can run it below 6 min. so a 4 min kilometer is not very hard

our cross country team this year posted times of around 20 minutes.  The top 5 on our team usually got around 16:30.  But thats high school athletes.  Start aiming for 20 or so and as you run more, work your way down.  Also for long-term energy.. eat all types of pasta.

In a 400, at a meet when you're going for time, this is how I have best been coached...you stride out (take long steps but maintain speed) the first 100-150.  Then begin to accelerate on the back stretch into the second curve, and flat out sprint the last 100-150.  If you become conditioned enough you will be able to sprint the last 200.  Of course at high levels it is a sprint the entire way, but not in most cases during high school.   Good times: for a guy in high school 43 to 47 seconds is really fast.  41-42 would possibly win state at a 5A meet. \ngirl: you're lookin at low 50's as a very good time, mid 50's also would take some meets.\n\n800 meter:  Guys: 1 minute 40 seconds give or take a few seconds\nGirls: right under two minutes is cruisin.

35-40 in a 25 mile an hour school zone is not speeding a little. Whether you can get out of this or not I would recommend you watch yourself speeding. At that speed a kid could step in front of you and you would hit them before you realized you did. I do not think that is something a 16 yr old or anyone at any age would want to have to live with. The speed limit is set for the reason of maintaining the safety of our children. The officer is allowed some leeway in estimating your rate of speed and probably you can get it knocked down to 10 over, pay the fine and quit speeding. May be one of your own family you hit.

400m = 16 lenghts in a 25m pool or 8 lenghts in a 50m pool.  the skill is to head to the pool and at a comfortable pace see how many you can swim then youl know what level you are at.  the key is to swim maybe three times a week and each time add one or two lenghts to what you previously swam..this allows you to build your strenght over time!then once you reach the 400m keep practising and it will allow you to go faster, i dont know is there a time limit? best of luck and im sure youl do fine!
