Answer:
more than half, by 0.5 seconds
Step-by-step explanation:
In his 200m dash in the 2008 Beijing Olympics, he ran it in 19.31 seconds. If he ran 9.68 seconds in his 100m dash, he would have ran more than half his time in his 200m dash.
If you were to calculate his 200m time subtracted by his 100m time, they are not equal, but the answer would be less than his time he ran in his 100m.
19.31 - 9.68 = 9.63
