i want to do it =(Why aren't you doing it?
Post by: naved_s9994 on August 04, 2009, 06:32:06 pm
Im doing it.
Since this is viewed by many people,
i am keen on asking everyone this.
Q. What stratergies are undertaken by people.
Ive been doing this each year since yr 7....got 1 credit in year 8, and all borderline distinctions for the rest,
Like, any stratergies especially for the last..5 marks questions etc etc
Much Appreciated!
Post by: EvangelionZeta on August 04, 2009, 06:39:58 pm
Got a prize year 7-9, and a distinction last year, so it works. :)

i remember seeing this problem ages ago. the way i did it back then was to assign each tyre 1 'hitpoint'. each kilometre travelled would reduce the 'hit points' of the front tyre by 1/40k and the rear tyre by 1/60k.
obviously if you switch the front and back tyres after x kilometers travelled, you will get more than 40k.
so the question is to find the x at which you should switch your tyres, such that they will reach 0 hit points at the same time. which happens to be the harmonic mean of 40k and 60k, which you will see if you do all the algebra.
btw, is this a 11-20 problem or 21-30 problem?
not in hs anymorei want to do it =(Why aren't you doing it?

...BUT
Q. If the wheels on the front go till 40000Km for eg.
Then, we'd have to change to the rear ones. I.e now they can go till 600000Km.
However, those wheels on the rear have also already run 40000Km, and when they are placed on the front
they cannot create a futher distance of travel?
So, they can is on halt? I.e D?
Help lol, any justified answers

I agree with zzdfa
Assign each tyre HP of 1
Each kilometre at front will take off 1/40k and each at back will take off 1/60k
let x = kilometres tyre spends at front until change
let y - x = kilometres tyre spends at back until change where y will tell you how long the tyres last
Create two equations for each pair of tyres (front --> back and back --> front). Solve simultaneously for x and y. You get y = 48000.

TrueTears, how many prizes does Scotch get every year on average? I'm interested in comparing, since Scotch is reputably the better maths/science school between itself and MGS...
Post by: TrueTears on August 05, 2009, 10:38:59 pm
Our year 11 3/4 Methods class is pretty much forced to do this. :pHmmm, I'm not quite sure because I didn't do it last year due to sickness, but the year before I think around 6 - 8 people got it.

SOOOOOOOOOOOOOOOOOOOOOO EEEEEEEAAAAAAAAAAAAAAASSSSSSSSSSSSSSYYYYYYYYYYYYYYYYLOL SOHHHHHHHHHHH EASYYYYYYYYYYYYYYY I CLEANED MY ROOM.
lol anyways, it was ok, kinda guessed 2 - 3 of the questions, but for the 6 mark no multiple choice question, (Q 26), so pissed, I spent about 10 mins doing it, got the right working at the end but can't do a 2+4, and missed the answer by 1 ffs z.z.z.z.

SOOOOOOOOOOOOOOOOOOOOOO EEEEEEEAAAAAAAAAAAAAAASSSSSSSSSSSSSSYYYYYYYYYYYYYYYYare you serious about this?
did anyone get many of the last ones correct?
i hhad to guess about 5-6 of the MC and couldn't do any of the last ones where you had to fill in numbers >:(
Post by: EvangelionZeta on August 06, 2009, 03:33:46 pm
I did all of them up to 20, got 23 and 27 then guessed the rest.

I did it by similar triangles.
Post by: mandy on August 06, 2009, 03:45:15 pm
I did it by listing all the multiples of 6. The last digit of the number has to be 8 (or it doesn't work), so the last digit had to be 8. From there, you check out what multiples into a sequence with ascending numbers. Still kind of trial and error, but at least there was a "strategy". ^_^;
That was exactly my strategy!
Post by: TonyHem on August 06, 2009, 03:48:25 pm
Didnt even do the last 5 questions really - just chose random numbers ;S

just wanna have a look @ it since I didnt do it cos I was doing a SAC :S

You're allowed references/calculators? >_>
yeah, only at my school because we dont have carpet or tiles. We had to paint the dirt green.

LOL YES I AM JOKING
It was hard as, I guessed quite a few
Post by: /0 on August 06, 2009, 07:22:41 pm
It was quite hard! The fill in the numbers bit was hard. The reciprical question drove me insane, and so did the train station one.. And, that ascending number one. Was there an easy way to do it? I did it by trial and error, but finally got it, lol.
lol some guy at my school took 3 guesses and got it on his third try, 578 :P
