The apostrophe should be placed after "swimmers" to indicate possession. The correct form would be "all three swimmers' laps are very strong," meaning the laps belonging to the swimmers are strong.
There are three types of apostrophe. The possessive apostrophe, to show that a letter is missing and to highlight a word or phrase, eg 'hasn't', doesn't', 'can't'. The possessive apostrophe would be used in a sentence such as 'The student's work was of a high standard' meaning the work of the student. However if you are using the word students in the plural form, it would be written 'students' work'.
That depends on how you're trying to use the word. See the sentences below for examples: 1) I have 30 students in my class. 2) I have 30 students' books in my class. 3) I have this student's homework slip. Sentence one has an S because it is indicating plurality. Sentence two has an apostrophe after the S because it is indicating plurality and possession. Sentence three has an apostrophe S because it is indicating singular possession.

Well, honey, there ain't no such thing as a three-letter word with an apostrophe. Apostrophes are used for contractions or possessives in words, but they don't just hang out in three-letter words for fun. So, you can keep searching, but you won't find any three-letter words strutting their stuff with an apostrophe.
I've is a three letter word. I'll is another three letter word.
The three cases for nouns are:Subjective (nominative) nouns are functioning as the subject of a sentence or clause.Objective nouns that are functioning as the object of a verb or a preposition.Possessive: (genitive) a noun that shows that something belongs to it; possession is shown by adding an apostrophe 's' to the end of the noun or only an apostrophe to the end of some nouns that already end with 's'.
