C and D set out first. D carries the torch. As soon as C reaches after 9 minutes, A sets out. A and D reached the other end at same time at t equals 12 min. D passes the torch to A at t equals 12 and steps off the bridge. A stays on the bridge near the destination side. At t equals 12 B sets off for the other side. At t equals 16 B reaches the destination. A and B step off the bridge at exactly 16 minutes.

And the fat lady bellowed.

I don’t think staying on the bridge is allowed. Likewise, I don’t think walking halfway is allowed either. But that is an incomplete problem statement for you…
