It depends on who is answering the question. "Fast" is too ambiguous.
11 seconds or so
A 12 year old's average time for the 100 meter dash, should be about 15 or 16 seconds.
14.00-16.00 seconds
im 11 and ran it in 11.97 im 11 and ran it in 11.97 ^Really? The word record for women is 10.49 seconds. You must be a super-human /sarcasm I'm 11 and I ran it in 15 seconds. I think that would be about average.
100 meters / 11 seconds = 20.336 mph (rounded)
To find out how many mph is 100 yards in 11 seconds: First, convert 100 yards to miles (100 yards = 0.057 miles). Next, calculate the speed by dividing the distance (in miles) by the time (in hours) - 0.057 miles / (11 seconds / 3600 seconds) = 19.64 mph.
It took Eric: (11*60)+44 = 705 seconds
88 seconds
He can run 100m in 11 seconds.
9.09 m/s
11.99 seconds because 100 yard dash is 91 meters. 100 meters/91 meters = 1.09 Then do 11 seconds x 1.09 = 11.99 seconds. If you round it, you basically be getting a 12 second 100 meter dash.
Yaniv Gershom in 2011 Overland Park, Kansas. 11.8 seconds in the 100m dash. Haha. Dude thats slow. The fastest time I have seen by an 8th grader is 11 seconds flat. The second fastest i have seen is 11.4 It doesn't really get much faster then that.
