Answer:
0.3
Step-by-step explanation:
In order to find the mean, you need to add the five times for each team and divide by 5, then subtract the two.
12.1 + 12.2 + 13.7 + 11.2 + 12.1 = 61.3
61.3/5 = 12.26
11.3 + 11.7 + 12.1 + 14.5 + 13.2 = 62.8
62.8/5 = 12.56
12.56 - 12.26 = 0.3 second difference
Hope this helps :)
