between what distances does a sprinter in a 100m sprint reach top speed?

[JesslIca]

This is according to Hill (1927)

i have the options of :
30 and 50 m
24.7 and 47.5 m
50 and 70m
13.7 and 18.3 m
27.4 and 45.7

Ive asked just about everyone and nobody knows, my guess would be 30 and 50, but i dont know,any explanations as to why aswell,. i dont need to know but i want to for next time

thanks xx

in a 100m dash sprint, i think it would be best if we analyze it first. im putting myself in that situation, let see.. around the 30m mark, i think im still not reaching top speed, maybe just maybe around the 50m ti 70m mark, then the rest would be maintaining ur speed i dunno, just got nothing to do.. hahah.. thats my opinion!
