Pow C: "Crossing The Bridge"

Pow C: "Crossing the bridge"

Process: The first step I took in trying to figure out the shortest amount of time was to just start guessing. I put a whole bunch of stuff together. I tried different ways with different people going with each other at different times. I ran into some high minutes but then I also ran into some low minutes. I had minutes as high as 27. Each time I would make a new way and the minutes would get lower and lower until I got to 19 minutes. I was certain this was the answer because I could not think of a better way. My conclusion was that Ally and Doretha would walk over which would be 10 minutes and then Ally would walk back which would be 1 minute. Then Ally would take Brian over which would be 2 minutes. She would then come back which would be another minute. She would finally take Carlos over which would be 5 minutes. Therefore it would all add up to 19 minutes. After a couple of days I decided to go back over my Pow to make sure I was completely right. It came to me after a little deliberation. The lowest amount of minutes you can have is 17 minutes.

Solution: In conclusion, my solution as to what the lowest possible amount of minutes there can be is 17 minutes. The way this would work is that Ally took over Brain which would be 2 minutes. Ally would than come back which would add another minute. Carlos and Doretha would walk over the bridge and that would take them 10 minutes. Brain would come back after them which would take 2 minutes. Finally, he would take Ally back over which would than be another 2 minutes. Another way for this to work is if you switch the roles of Ally and Brain. It would take them the same amount of minutes for them to cross the bridge as before. In the end, I believe there are only two options for the lowest amount of minutes.

Evaluation: In my experience with this Pow, my personal opinion is that I didn't like it
