In your 55 meter dash, you hit the 40 yard line at 4.62 seconds. However, you ran an additional 20.14873 yards after that. If you had actually run a 40 yd dash instead, you probabaly would have been sightly faster then this (around 4.60 maybe?), but this depends on your stamina, power and accelleration. There really is no set calculation you can use, especially in short races such as this.
A simple answer would be to just say that it would be 40/60th of 6.8 so approximately 4.53 but that would not be actually right. That would only be correct if you were moving at the exact same speed the entire run and you don't when you are racing, you have a top speed that is the majority of the run but you have to consider the time it takes to reach your top speed.
You would have to time yourself running it.
Running 40 yards in 4.2 seconds is equal to running 19.5 MPH.
A 6.8 second 60-yard equates to a 4.53 second 40-yard.
Barry Sanders 40 yard dash time is 4.37 seconds. They said that Bob Hayes did not run the 40 yard dash but they say it took him 5.28 seconds to run 60 yards. So I would say that Bob Hayes is Faster.
-30
You can't. It would be like extrapolating a marathon time from a mile time.
There is no record for Bob Hayes in the 40, but the late ESPN.com columnist Ralph Wiley once wrote that Hayes reportedly ran a 60-yard dash in 5.28 seconds on a cinder track. In the 1964 Summer Olympic Games in Tokyo, Hayes won the gold medal in the 100 meters at 10.05.

Time = Distance/Speed = 40/60 hours = 40 minutes.
