The difference between his best and worst time is: 0.11 sec
Step-by-step explanation:
We have to subtract the smallest time(best time) from largest time(worst time).
So,
Largest Time = L = 23.45 sec
Smallest Time = S = 23.34 sec
The difference will be:
[tex]d = L-S\\= 23.45 - 23.34\\=0.11[/tex]
Hence,
The difference between his best and worst time is: 0.11 sec
