1 hour to get ready means time to shower, dress, make food to bring to work. Clean up litxhen because pots pans and food left for over 12 hours is not good. 1.5 hour drive (45 min each way min, assume no traffic accident). It adds up to 24: 3.5 + 2.5. = 6. Add that to 6 hours max sleep, is 12. And the 12 hour shift is 24 hours .
