100 Meter Dash

yes.

Question: Who was the last man to hold both the 100m and 200m world records at the same time? Answer: It was Ray Norton of the United States. On April 18, 1959 he tied the world record of 10.1 in the 100m in San Jose, California, USA. Then on April 30, 1960 he tied the world record of 20.6 in the 200m in Philadelphia, United States. Therefore on April 30, 1960 he held world records in both the 100m and 200m. Since then no man has held the world records in the 100m and 200m at the same time, until Usain Bolt in 2008. Almost 50 years later! Bolt set world records of 9.69 in the 100m and 19.30 in the 200m at the Olympic Games in Beijing China in August of 2008. -Asad Raza

One yard is the same as 0.9144 meters.

60 yards is equivalent to about 55metres, so it will be a little bit below 6.9 maybe?

That is amazing! You are a very fast runner, and should join track when you get older. That is very fast. Why you would have any doubts of yourself being fast I have no idea. You have a knack for running, and you should definatley keep it up! -Minicooper out!

Not sure exactly but around 1 minute flat. There have been many girls near the top of the world in swimming at around 15 years old so the fastest ever will be quite fast.

The first world record for the 100 metres took place in Stockholm Sweden on July 6th 1912. The time was 10.6 by a man called Don Lippincot from the USA. It was duplicated (10.6 again) by Jacklin Scholz, again in Stockholm on Sept 16th 1920.

His best 100m time was 9.87s

A time of 15.1 seconds in the 100 meters for a 12 year old is a good time. It is not considered especially fast, but it is likely as fast or faster than average.

between 55.4mph.- 89.4

1 meter = 1.0936 yards (rounded)

You can but your time would actually be slower than if you just sprint through. The best way is to lean as you break the finish line.

Would probably depend upon the gauge of the cable, the type of metal used to conduct the electricity, what kind of shielding/jacketing around the wire, and how many breaks there are in the cable i.e. crimped butt connectors if applicable.

When I was an eighth grader i ran 13.1. Now i am a junior in high school and i run 10.9. I would think a good time for an eighth grade boy would be around 14 seconds and for a girl around 17 seconds.

*the following is an addendum by a local Pediatrician from Los Angeles, Ca.

The question supposes that ALL 8th grader's would be the appropriate age for someone in the 8th grade. Many kids in 8th grade ARE 13 years of age, and many of them turn 14 while in 8th grade, but some such as myself begin 8th grade at 12 years turning 13 years of age within a couple of months. Far fewer kids turn 15 while in 8th grade, and just a handful will turn 16 years of age while in 8th grade. That said, a much MORE ACCURATE rating for how well an individual achieves is to use their AGE since there is NO SET AGE TO BE AN 8th grader AND we all know that for boy's who are 12, 13, 14, 15, OR 16 that physical maturity vastly differs...

*

It is really a dishonest measure to rate a child's physical achievement's by which grade he is in since parents are the one's responsible for starting their child into 1st grade and as we can see those ages differ over a wide range. WE SEE newspaper's and websites breaking results down by grades because that is how schools align the competition. To rate and praise a child for a physical feat based on their GRADE ALONE is not fair to your child and smacks of Egotism by the parent.

*edit... 17 for a girl?? That is an insult! Haha. Lots of even 7th grade girls can get like 10 seconds. I am in 8th and I am getting better every time...

9.6 secones

100 meters/9 seconds = 40 kilometers per hour = 24.85 miles per hour (rounded)

My daughter is in fifth grade she is eleven she does a min nineteen she is best in her grade from girls. an excellent time for a first grade is one min 35 but for a four year old maybe two mins is really good.
