easy! person 1 accompanies on every trip

and saves a minute Wink
Erm:

A & B go across - 2 minutes.
A goes back with torch - 1 minute.
A & C go across - 5 minutes.
A goes back with torch - 1 minute.
A & D go across - 10 minutes.

2 + 1 + 5 + 1 + 10 = 19.

How did you mean? How did you "save a minute"?
