What Distance Our Predictions Current World Records
100m 9.5secs 9.58secs
200m 18.7secs 19.19secs
400m 40.12secs 43.18secs
800m 104.2secs 101.09secs
1500m 211.secs 206secs
We found this out by dividing the 40 year difference between 1908 and 1948 by 10 so you get the differences every 4 years and then multiplying them by 16 because there are 16 4s in 64. We do it into 64 because there is 64 years between 1948 and 2012.
For example in 40 years there is a difference of 0.5 seconds for 100m, so every 4 years it will be 0.05 so we multiplied it by 16 and took it away from the original time in 1948 (10.3-0.8=9.5seconds).
