Brain or brawn?

[pericat]

You have 4 horses, all of which travel at different speeds. In travelling from A to B these horses take 1, 2, 4 and 6 hours respectively.
On day, you decide to move all your horses from point A to point B. however you can only move a maximum of 2 horses at a time and you need to ride a horse back to point A each time you return to move your other horses. Knowing you can only move as fast as the slowest horse you're travelling with, what's the fewest number of hours it will take to complete your move? Have a good afternoon all!

start off moving the 1 and 2 hour horse over then take the 1 hour horse back, move the 4 and 6 hour horse over and take the 2 hour horse back and then finally take the 1 hour and 2 hour horse over.

13 hours

[pericat]

And Ankou gets an apple or did Dot tell you ?

[ABerrant]

A(1) & B(2) = 2
A(1) return = 2 + 1 = 3
C(4) & D(6) = 3 + 6 = 9
B(2) return = 9 + 2 = 11
A(1) & B(2) = 11 + 2 = 13

[dothawkes31]

correct, that's exactly how i got the bears answer : ))

[pericat]

I have given answers to the first four yogi - will stretch the brain now and be back to you

[monkeyeyes]

I should have taken a little more time to consider the permutations.

[Barmaid]

Loved this question, but didn't have the mental capacity to work it out. So I would have just hired a box and moved two at a time!!!!!!

[pericat]

Lol barmaid - that thought did go through my mind
