Re: Four People Travel Puzzle

Hi MIF;


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

hi MathsIsFun,

One of my early posts raised this question.

I got the same three answers then.

Re: Four People Travel Puzzle

hi Stefy,

True.  Our paths have wandered erratically without crossing for some time.

I've also been elsewhere.  Firstly, I went to New Zealand for a touring holiday.  We stopped over at Singapore on the way out.  My posts to MIF forum were somewhat limited by availability of wi fi and an i-pod.  I found it really hard even just typing without errors and diagrams were out completely.   As you may have noticed that makes most of my help impossible as I have a high diagram rate in posts.

Then we went to visit my grandson, James, and his parents.  There's a picture in another thread.  I'm sure you can track it down.

Then I got 'promoted' to moderator.  Suddenly, there's a heap of new things to learn about.

And I've bought a new laptop, which means I have a daily battle making it bend to my will!  smile

Re: Four People Travel Puzzle

I think there is one and only one solution.

John gets seasick so he must be on the ship.
Cindy had to rent so she is using a car.
Mr. Jones hates flying so he booked the train.
Rachel is therefore on the plane.

Re: Four People Travel Puzzle

Seasick means he gets sick when sailing on the sea, that means the last thing he wants to do is choose a ship as his mode of transportation.
