    Correct! An inspired answer. Now which one has nocturnal interests?

    Yes ! I had a feeling you'd get that one.
    Your turn.

    I've got a good Dictionary of Greek and Roman Mythology.

    OK - another puzzle - how about this one:

    Town A is a hundred miles from Town B. A straight railway line connects them. Every day at mid-day, a train leaves Town A and travels to Town B at 60mph. At the same time, a train leaves Town B and travels to Town A. This train is not so fast and can only travel at 40mph.

    One day, a bird who has nothing better to do decides to fly with the train from town A until it meets the train from Town B and then hitch a lift back to Town A with the train from Town B. This super bird, who has certainly had his Weetabix for breakfast, flies at 70mph so, of course, overtakes the train from Town A and when he arrives at the train from Town B, he decides to fly back to the train from Town A instead of hitching the ride. When he gets back to the train from Town A, he's having so much fun, he turns round and flies back to the train from Town B - and so on. He keeps flying between the trains until they meet when he reverts to his original plan and hitches a lift on the Train from Town B back to Town A. He's exhausted - of course he is, he's flown - how far before the trains pass each other? (Yes, it's a double track, the trains don't crash into each other.) And what time did the trains pass? And what time did the bird get back to Town A?

    MM - One of the times is right, but which one and how is it right? And how far did the bird fly?

    As for the bird: is it possible the answer is "0 miles", as it ended up back where it started?!

    Only if you can convince me that when I go to work and back each day, I've been nowhere at all.

    Here are my thoughts. You don't need maths hardly at all.

    The trains will meet I hour after setting off.

    At a point 60 miles from town A and 40 miles from town B

    The bird must have travelled 70 miles in that hour (as it is going at 70 mph)

    The bird arrives back at the sheduled train arrival time. (100 miles at 40 mph, which is 40 miles in 60 mins, which is 1.5 mins per mile, which is 150 mins total train journey time, which is 2hours and 30 mins

    So

    The trains pass at 1 O'clock
    The bird flies 70 miles
    and arrives back at 2.30

    As got by faithosaurus

    That's right, faithosaurus and Mick - and you're right, Mick, it isn't really a maths question, it just looks like one. I got it from my educational Psychology lecturer years ago - he used it as an example of 'set' in thinking (or is it 'sett'?), (eg it looks like a maths problem, therefore I must use a mathematical approach, rather than what's the real problem here.)

    Over to you, Mick, but I must bow out here as I'm away in a computer-less home over Christmas - yes, they do still exist! Happy Christmas, everyone.

    Here is one I heard years ago, a simple maths question with an almost unbelievable answer


    Take a rope and pass it once round the world. (say 25000 miles) Pull it tight, then let out 6feet. As this is magic floaty rope, how far above the surface of the earth will that 6 ft of slack allow it to float.

    Now do the same with a tennis ball, (say 10 inches)
