An airport-inspired puzzle

I liked this response from professor shoelace:-

Professor Shoelace

“Is it more efficient to do so while on a walkway, or off the walkway?”.

If our ONLY concern is the total time taken to get from A to B, then pausing to tie while on the walkway is indeed both intuitively and mathematically a “more efficient” use of our time.

Personally, I believe it would be “more efficient” to tie your shoes immediately upon noticing that they had come undone, regardless of whether that occurred on a walkway or not. That way, one’s energies could be devoted to pondering other more worthwhile things (such as mathematics) rather than concentrating on stepping carefully to avoid an accident due to an untied shoelace.

For even greater efficiency, those who regularly suffer from untied shoelaces would be well advised to Google the problem. The short time spent learning a better shoelace knot will invariably be far less than the combined times of thousands of re-ties over the space of a lifetime.

DOH

In hindsight it's obvious the two biggest slow coaches should cross together.

Hindsight - Wonderful thing!
PS - I am the lardy slowcoach!

[OwlHoot]

Well to be fair - I don't think its right to say "Everyone assumed that A has to come back all the time".

Mich gave you the answer (albeit sneakily) about 10 mins after you posted....

OwlHoot - Bragged about how easy it was (although he was spouting bulltulip)
ASB - Told him he was wrong (which suggests that He knew the real answer)
I - (also) Implied OwlHoot was shot down flames (suggesting I knew the answer)

Don't you read any of this stuff!!

Two minutes in heaven is better than one minute in heaven

Depends who else is there.

I'm a very efficient love maker, it's not my fault if she can't keep up.

See Pondlife's answer above.

Everyone assumed that A has to come back all the time...but not so.

A+B = 2 mins.
A comes back = 1 min.
C+D = 8 mins.
B comes back = 2 mins.
A+B = 2 mins.

= 15 mins.

doh of course

i am thick!

ok

so we need to cross the bridge with all 4 people

now given the question it will take

8 mins for D
4 mins for C
2 mins for B
which is 14 mins
in between times a has to come back two times

so you get 16 mins (or secs)

unless obviously a is strong enough to carry b, c and d in which case you can do it in 5

go on do tell the answer.....

Has noone done it yet?!!!

Alex and Billy cross = 2 mins
Alex returns = 1 min
Claire and Denise cross = 8 mins
Billy returns = 2 mins
Alex and Billy cross = 2 mins

Total = 15 mins.

Obviously this could have been avoided if the women had worn some more suitable shoes or had enough room in their handbags for another torch...

I've only been to Sands once, a girl gave me a black eye.

Didn't you realise you'd pulled. They just get a bit rough with the foreplay.

There used to be "gentlemans" club on Broadway - don't know if it's still there. I ended up in there very pissed with some mates a few years back. The topless pool was very comical. I think sky should televise it.

Not been for a couple of years, but it always used to be good (if you like greek of course). So convenient to nip round the corner to sands for a figt and a stabbing after too. I think sands is rather better these days but when I used to go about 10 years ago it often got pretty scary.

Dimitri has a Bistro in Uphill too, both restaurants are good.

My mum rang yesterday to tell me the Greeks have got the Cabot… talk about small town mentality.

You have to do it in 15 seconds, not 16.

Exactly.
