hard to tell with these threads without PRs or other workouts. it's a good workout. not a 5k workout but not a true 10k predictor. I would assume you're sub-16 for 5k so I would guess, at minimum, that you can go 34-flat-ish. Anywhere from 33:30-34:30 but, depending on your background, other workouts, how easy it was, I can see a runner doing this workout getting down to 32:59.
