I worked this out by first finding the difference between the 40 years which was:
100m -0.5 sec
200m - 1.5 sec
400m - 3.8 sec
800m - 3 sec
1500m - 11 sec
Next I calculated 64 divided by 40 which equals to 1.6
After that I done 1.6 times all the answers and then minus it from 1948's results.
I got:
100m = 9.5sec
200m = 20.2sec
400m = 40.12 sec
800m = 104.2 sec
1500 = 211.4 sec

To solve this problem I firstly found the difference between the results from 1908 and 1948. Then I divided 40 by that answer. Next I timed that answer by 64. Finally I took away then my result from the 1948 result.
E.g. 100m sprint-
0.5 ÷ 40 equals 0.0125. 0.0125 × 64 equals 0.8. 10.3 – 0.8 equals 9.5.
So therefore in the 2012 Olympics, the time expected to complete the 100m is 9.5 seconds.
My Results were:
100m- 9.5sec
200m- 20.2
400m- 40.12sec
800m- 104.2sec
1500m- 211.4sec
