Did anyone get anywhere with the simplification?
Wouldn't you think that the level of difficulty for such a problem should fit the purpose? I mean if you want to see if someone can solve a system of equations, why does it have to be such a large system?
Mikau, by the way it is irspow and not irspower. The I.R.S. already has unconstitutional power, it does not need any praise from us. My name is irspow, as in I.R.S. and P.O.W. and it has been the same on the internet for over 15 years.
I plugged the above refuse into my TI-89 and 20 seconds later it solved for B. Even then it spat out a implicit function which is useless because you need B to use it.
Great minds think alike. I think that you got all of the same foundation relationships that I had. Now the hard part is upon you. When I started to rearange these formulas is when I got a headache. I have still not stumbled upon the combination which yields a single variable. That is why I told Graeme that even one more piece of information would have made this problem much easier.
Isrpower, as you can see I also got 10 relationships. Did you get one I didn't get?
Oops. The position where the boy saw the cyclist on the graph I drew is obviously wrong. But fortunatly, that should have no effect on the truthfullness of the equations. (if I did them right in the first place)
Well I managed to crank 11 equations out of this problem. There are 11 variables to consider so it should just be a matter of rearranging now. But I'm too exhausted to do it at this point so I'll just post what I found for now.
Mikau, I assumed it was two hours AFTER passing the jogger as well....but judging at my track record lately it probably is not the case. (That was supposed to be funny darn it!)
I hate when the wording is debatable!
I am not sure, I can only assume that it is from when he passed the jogger.
I'm confused about the wording of this problem:
I am looking forward to the solution as well. I am relieved to hear that it wasn't some sort of pipe dream. If it is solvable without a computer program then it is a very good question indeed. It has left me baffled so far.
Oh I can assure you that I didn't make this one up off the top of my head. This came from a small maths paper and I will be waiting in anticipation for the "solution".
