the fastest 100m dash was set by usian bolt with 9.69 seconds and for many olympic athletes their time averages around 10-11 seconds
I would say around 15 secounds would be average. Hope that helps! :D
5.1 m/s
Three seconds on the 100m dash!
the average speed is 6.67m/second
About 9.5 to 10 seconds.
22.92 mph.
24.87mph
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.
Approx 45mph
