I wonder what Hussein Bolt could do in a 40 time.
Well, in the Olympics, Bolt's splits in the first 30m were...
10m, 1.85 sec
20m, 1.02 sec
30m, 0.91 sec
Bolt covered 30 meters in 3.78 seconds. 30 meters is equal to 32.8 yards.
So, Bolt has another 7.2 yards to cover before we can figure out an estimated time. Bolt's next split was...
40m, 0.87 sec
As a rough estimate, Bolt covered those 10m at the rate of 1m every 0.087 seconds. 7.2 yards is equal to 6.584 meters, so we multiply the distance in meters by Bolt's velocity and we get .5728 seconds.
Add .5728 to 3.78 and you get...
Usain Bolts 40 time - 4.35 seconds.
Edit: The 4.35 time is off of a gun, if Bolt were able to start running when he chose then obviously his time would be lower. Bolt's reaction time in the Olympic 100m race was 0.165 seconds. So, if we subtract that from 4.35 we get Bolt's "combine" 40 time of...
4.185 seconds
Bolt's speed really kicks in at 50m and his flying 40 yard time when he's running at top speed is right around 3 seconds flat, 3.01 if you're rounding.
