    The answer for question 2 (answer: 20) is questionable. How can the exact minutes be determined using an average speed?

    Average doesn't mean approximate... The speeds and times did add up suspiciously neatly. Iain.

      Before being allowed to use one rotted my brain I was able to do problems like 98*76 or 9*876 in my head faster than anyone could tap the buttons on the idiot box and win about half the time with problems like 98*765 or 9*8765. If I wanted to show off I could do problems like 9876*54321 too but had no chance of beating a button masher. My informal test for how clueful grade school teachers were was to see how long it took before they realized that if they were going to offer a prize for a basic in class math-game (generally flashcard speed) that unless they offered them for the top two spots they might as well just save some time and give it to me at the start of the day.

        You are correct. I got the idea. The average speed by speedometer was based on the actual time and distance she traveled.

            ok how did I miss 2. I think the answer to # 7 is wrong. I chose what they said was the correct answer but.. You could not Physically have 6 people coming in at the same time. 4 at the most. I think # 9 was wrong also. I could have sworn I chose the smallest number. Is 26.5 larger or smaller than 26.58 ?

              It is an adaptive quiz that takes into account your answer as well as how long you take to answer. It stopped after 10 for you because it didn't think you can handle any of the harder questions. :)

                  On #7, that's a very astute observation! The obvious solution, and the one most of us used and were scored as correct, is that all three compartments are full. But of the three, only two will be entering; one will be filled with people leaving. Your answer is technically correct in a real world sense, but when has a mathematician concerned himself with reality? :-D On #9, I don't know which you picked, but 26.58 is clearly 0.08 larger than 26.5. It is normal practice to omit trailing zeroes unless a fixed width format is specified.

                    I picked "A" but without looking at the chart again I can not be sure what the numbers were. If I remember correctly the last 2 in the chart were larger than the first 2.

                                  The less you answer the higher the mark you get, this will decrease the possibility of errors.

                                    That's the only one I got wrong, as I missed the "in cm" bit at the end. Not really math, more reading. Iain.

                                    Yep, I almost missed that one, too. But then I'm used to specifications arriving late ;P

                                    GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

                                      9/10, but surely the right answer here is 8am? 18km at 1.5 km/h will take 12 hours? The Gotemba walking trail up Mount Fuji is about 9 kilometres (km) long. Walkers need to return from the 18 km walk by 8pm. Toshi estimates that he can walk up the mountain at 1.5 kilometres per hour on average, and down at twice that speed. These speeds take into account meal breaks and rest times. Using Toshi’s estimated speeds, what is the latest time he can begin his walk so that he can return by 8pm? 10am 11am 12pm 1pm

                                          I haven't owned a Calculator in my life. Does that make me a genius?

                                          so you don't own a mobile phone - I haven't seen one, not even a dumb one that doesn't include a calculator - or a PC - Windows comes with one, every version of Linux I've seen also does, I suspect Macs do as well. So I'll go with the poor option as well.
