    It asked for the lower bound starting and ending at Y. That means delete arcs attached to Y. So surely 102 and not 118.

    I got 295 as weight of cycle was 130, weight of the stops was 30x5+10+5 so 165, add them is 295.

    Weight of cycle 130 right? So surely 165 waiting time as you wouldn't wait at Y

    The stops in the questions were as follows:

    2x5 minutes, 1x10 minutes and 5x30 minutes. You need to stop at Y so the visitors could look around the place

    Very poor mark scheme:
    I just typed number that I saw on my paper into my calc, pretty sure the pageboy bit is wrong but oh well...

    Oh right I though the waiting time was for rest time, didn't read the question properly...

    For the last question it asked for a close route is that the same as a closed cycle? I assumed it meant you didn't have to back to the start but from looking at this I don't that is correct.

    You had to go back to Y.

    I've been looking like a complete tit for the past hour by saying 'Percy Li' in a variety of different tones, accents, volumes and speeds in order to see if OCR chucked in another pun (remember Roland Kneede the baker and Rhoda Raghe the avid driver with a horrendously contrived surname?). Anybody made any progress?

    iirc the question was about road maintenance?

    I'm glad I'm not the only one who did this
