100 Meter Dash

Effective distance run = 100 m + (9.84 x 0.5) = 104.92

Effective speed = 104.92 m per 9.84 s

Therefore with no wind resistance, time to cover 100 meters = 100/104.92 x 9.84 = 9.3786 (9.38) seconds.

LOL:)

The average oline 40yard dash is 5.24 sec.... 4.6-4.7 is prestige

I am 11 and I personally don't think that I run fast. In P.E., we do mile runs almost every time (every 2 days) and I feel like people are definitely getting better. It really matters on how fast you are and how much strength you have. Here is the average for boys and girls in my P.E. class.

Boy:8 minutes

Girl:6 minutes

U.S. runner Florence Griffith Joyner with a 10.49

my is 2:55 and i'm not joking

Cristiano Ronaldo can do 100m in about 10.61 seconds. The fastest football player ever is said to be amancio amaro who can do 100m in about 10.50 seconds.

what age?if you're talking about a 7 year old,it's 19.11 seconds

Well for an 11 year old it is 14.21 seconds

You cant earn money in the Olympics. The Olympics pay for a win with fame and a gold medal.

it is Jesse Owens in high school he ran the 100 yard dash in 9.4 seconds

Your time would be just about the same since a yard is 36 inches and a meter is 39.37 inches. 100 yards is 91.44m. With a time of 11.5 for about 90m, you are running on average 10m in about 1.28 seconds, making your 100m time about 12.78, given the same circumstances.

usan bolt

at aged 12 years of age i ran the 800 metres in 2mins 23.4 secs

Australian Nationals in 2010 were won in 2.06 in the 12 years boys 800. Jean Baptiste Tooley ran a 2:01.8 as an 8th grader at the 2011 CYO Chamionships in Portland Or.

100 yd dash at 11.2 is faster than 100 yd dash at 11.9!:)

There have been short, sprint races since the beginning of the ancient Olympic Games although history has not recorded when the first 100 meter dash race was run. The 100 meter dash has been part of the modern Olympics since the first Games in 1896.

100m, 200m, and 4x100m relay.

No one on record has broken the 3 minute mile in the last 116 years (since the first modern Olympics). Any records older than that are up for speculation since the mile was not always a standardized race. Here are a few cool stories though:

In 1870 a native American ran behind a horse for a mile. The horse was clocked at 2:40, the native American was not clocked. However, eye witnesses noted his distance behind the horse at the start and at the end of the mile as being very close to the same.

Ladas of Argos in the ancient Greek Olympics. No specific time was recorded, and the distance was 20 stades (about 2.5 miles), but the inscription on his statue says "His speed was demoniac, nor could it even be described."

Asahel from The Bible (2nd Samuel 2) during a battle, chased Abner running fast enough to impale himself on the butt end of a stationary spear which went through his entire body including the armor which he was wearing during the chase. The physics of such an account would suggest that a minimum speed of over 20mph (3 minute mile pace) would have been needed for the blunt pole to travel in one side and out the other side of his body through armor and muscle.

In England during the time of the Roman Empire (2nd century CE) entire tribes of warriors (with similar lifestyles to the native Americans) were noted as being able to catch and overwhelm horse riders while running on foot.

I would be difficult to get any of these, or the dozens of other accounts, to be recognized and accepted by modern scholars. And none of them could be labeled with an exact time or proven to be under a 3 minute mile, but they make for an interesting study.

My freshman 800 time was a 2:26, yet I am a mile and two mile runner. If your main event is the 800, a good time for a freshman would be between 2:05 and 2:15 or better than that. Anything else you would probably not place

Travis Padgett of Clemson University broke the collegiate 100 meter dash record by running a time of 9.89 seconds at the 2008 US Olympic trials.

Around 8 or 9 Seconds

Six ... 3 gold, 1 silver, and 2 bronze.

1984: Silver in heptathlon.

1988: Gold in heptathlon and gold in long jump.

1992: Gold in heptathlon and bronze in long jump.

1996: Bronze in long jump.

The advantage is that it is really short and won't take very long. The disadvantage is you will need to get up to speed very quickly in order to win.

well an average time for a 12 year old boy would be around 17 seconds

a good time would be 14-16 seconds

a realy good time wuld be 12-13 seconds

and the 12 year old record is around11.44

so there :)

The 800 meter run is a half mile or, on a standard 400 meter track, two complete laps.
