40 yard dash/10 yard dash= 4 What ever the time you got for the ten yard, you multiple it by 4. It could be an average of your running time per 10 yard dash. Sometimes for several runners, they would feel worn out by the time when reaching the 40 yard mark.
The 100y is rarely run outside the US, however, it is likely that Bolt will have passed the 100y mark in his best 100m race in around 8.75s.

Mathematically calculated Rose' 40 yard time is 4.48.This was calculated by taken Chris Johnson's 20 yard time and Derrick Rose' 20 yard time of 2.65 in which i got from http://www.muscleprodigy.com/derrick-rose-workout-arcl-1189.html and subtracting the two times and I accumulated 0.24 I added 0.24 to Chris Johnson's 40-yard time and that equaled 4.48.
