One Headlamp, Four Miners

Four miners — Petra, Quinn, Rosa, and Sam — must evacuate through a narrow escape tunnel that holds at most two people at a time. The mine's power is out, and the group has a single working headlamp; nobody can move through the tunnel without it, so after each pair (or person) exits, someone must carry the lamp back for the others. Their walking speeds differ: Petra needs 1 minute for the tunnel, Quinn needs 2, Rosa needs 5, and Sam needs 10. When two walk together they move at the slower person's pace. Petra claims the whole crew can be out in 17 minutes. Describe a crossing schedule that achieves this.
