the second question:
1 minute guy is the fastest, who will be the one run back and forth passing the flash light. This is the key
1 and 10 cross bridge - 10 min
1 return - 1 min
1 and 5 cross bridge - 5 min
1 return - 1 min
1 and 2 cross bridge - 2 min
------------------------------
19 min
let me give it a shot!
