The answer is: 100m 2012=9.75secs
200m 2012=19.5secs
400m 2012=42.4secs
800m 2012=106secs
1500m 2012=218secs

This is how I came to these results: First I worked out what the difference between 1908 & 1948 was, e.g. 100m 1908=10.8secs 1948=10.3secs=0.5secs difference. I then took 0.5secs from 10.3secs to find my estimate for 2012 and this is what I did for all the other questions. Even though there are 40 years between 1908 & 1948 and there are 64 years between 1948 & 2012, I think that the sprinters would not have improved the time at the same rate as at 40 years because thinking logically the human body can only improve so much.
