Problem Solutions




Himalayan Expedition Problem
The bridge can carry a maximum load of 200kg - there are 2 climbers with rucksacks each weighing 95kg. There are 3 porters, each weighing 70kg. 5 large supply packs weigh 18kg each and a porter can carry 2 packs. Work out how they can cross the bridge in less than 5 trips.


Some groups made models, some groups drew diagrams and some used a combination of both. We voted for the best 2 'presentations' and made a video of them for our Blog. James is the cameraman!

The Videos
The winning groups were The Formulas (click here to view) and The Denominators (viewed here)

Great ..... will get back as soon as our access to the Blog at school is allowed again!! Fingers crossed!

Has your video disappeared? That's happened here sometimes after going back in to make changes to the post??

Why does nothing ever turn out to be straight forward!!

Yes our video had disappeared -you're right this seems to happen if you edit the post.

It should be back now.


Our region blocks any site with the word blogs in it - I had to get them to allow both ours and yours.

(and is why I used Wordpress for our writing!)
