I would say around 15 secounds would be average. Hope that helps! :D
Three seconds on the 100m dash!
the average speed is 6.67m/second
About 9.5 to 10 seconds.
the 100m and the 200m dash, marathon, hurdles, basketball, football, baseball and etc.
100m/40s or 2.5 metres per second.
I was thinking the same thing but I found a solution:Basically 1 second= 0.00027778 hours.13mph- 0.06214(calculation of length of 100m)÷(0.00027778X13(your speed))This equals=17.21 seconds as your 100m dash time.It might look complicated but I simplified it.
Average speed = distance/time = 20 metres per second.
Usain Bolt fastest man alive 100m dash 9.58 oh and he is Jamaican.
it is a running event :)
the average speed is a 7.1 60 yard dash.
The average 40 yard dash speed for an CB in the NFL is 4.25 to 4.45
The start line from the 100M dash is 100M away from the finish line, parallel to the finish line.
A 12.5-second 100m equates to a time of 4.572 seconds in the 40-yard dash.
The 100m dash, 200 m dash, (sometimes) 400m dash, 100m hurdles, 110m hurdles, (sometimes) 300m hurdles, and sprint relays.
D=SxT 100m=Sx10s S=10m/s 1mile=1609.34m 1609.34/10m/s=160.934s=2.682233min 60min/2.682233=22.36mph
At 10.64 seconds, Carmeleta Jeter is the second-fastest woman in history in the 100m dash.
Here's some quick math... Might be wrong: 9.69 seconds is the record in a 100M race 328.08 feet = 100 M 33.86ft/sec for 100M converted to mph... 23.08mph average speed.
