The Question for others to try and correct me if possible:

The present value of a company asset is $350 000. If it has been depreciating at 17.5% per annum for the last six years, what is the original value of the asset, correct to the nearest $1000.



My logic could be wrong, but that is the question, and that is what I understood from it.

I just got my Cambridge book and checked the question- I remember this one- a nice but hard question.

Umm... I don't have time to latex a solution but I'll give you some hints which should help:
- What you should do is draw a diagram and work out the acceleration/speed/displacement for both the car and the truck.
- You can then compare the stuff you have to answer the whole question
- A way to semi-cheat is use your physics formulas (like v=u+at) etc. Although this is illegal and you don't do it in your final answer, if you use them initially, it can help you visualise the problem better and understand the relationship between the parts of the question. Make sure you do the final answer with integration and stuff though.

Hope this helps

Wrong question I think but I could be wrong.

I have a soft copy of it on my desktop, I just typed page 266 and there was q12 so I assumed it is the right question, but of course since you have the hard copy, its probably more accurate because my soft copy might have different page numbers or something.

Yeah that makes sense because a lot of soft copies sometimes cut out like some intro pages or whatever.

Your answer for that question was correct though

That's not the question?

It's important to type or upload a copy of the question for users who don't carry the books in question. That way future members of the forum can look on to solutions without needing the textbook in front of them for the original question
