It took Sammi 38 - 11 = 27 minutes to finish the race. However, since Sammi came in 11 minutes before Ali, this means that she actually finished in 11 minutes.
We can determine this by subtracting Sammi's finishing time from the time of the first-place finisher.
The first-place finisher finished in 22 minutes, and Sammi finished in 33 minutes, so it took her 33 minutes - 22 minutes = 11 minutes to finish the race.
Another way to solve this problem is to use the following equation:
Sammi's finishing time = 22 minutes + 12 minutes
The 12 minutes represents the difference between Sammi's finishing time and the finishing time of the second-place finisher.
Solving for Sammi's finishing time, we get:
Sammi's finishing time = 22 minutes + 12 minutes = 33 minutes
Therefore, it took Sammi 11 minutes to finish the race.
