Since he works twice as fast as she does, when working together he does 2/3 of the work and she does 1/3.
So in 8 minutes working together, he does 2/3 of the job. To do the remaining 1/3 of the job himself, he needs to work half of another 8 minutes, or 4 minutes more. So he can do the job alone in 12 minutes.
And since he works twice as fast as she does, the time it would take her to do the work alone is 24 minutes.
