You can put this solution on YOUR website!
x = number of laps she runs
6x = number of total minutes she runs
total time < 42
6x < 42
6x/6 < 42/6
x < 7
She ran less than 7 laps today.
If x is a positive integer, then it can be selected from the set {1, 2, 3, 4, 5, 6}
x = 7 is not part of the list
1 lap = 6*1 = 6 minutes
2 laps = 6*2 = 12 minutes
3 laps = 6*3 = 18 minutes
4 laps = 6*4 = 24 minutes
5 laps = 6*5 = 30 minutes
6 laps = 6*6 = 36 minutes
7 laps = 6*7 = 42 minutes

To the solution by the other tutor, I want to add that 0 (zero) laps is also a possible solution,
which is NOT EXCLUDED by the condition and should be, therefore, included to the list of possible solutions.
Also, the natural order of words in your post is violated, making strange impression.
Do you really want to scare your readers ?
