10,000ft a week

[GreenFlash]

I'm VERY rusty but if you have a calculator with Sin-Cos etc you should be able to work it out.


but If I remember correct Kms

9(Kms)x Sin 15= Height gain kms

So if I'm right and I can't guarantee that

2.34 kms approx 2340m just over 7000ft.

It has been the best part of 28 years since I last did this so I hope it's correct.

I'm very impressed, Ian - having quite recently taught trigonometry to some of my students, I can confirm you're spot on here (give or take a rounding error, and assuming the machine measures the "uphill" distance run which would seem sensible - viz. the hypotenuse - rather than the horizontal distance) ... any objections to me using the example in the forthcoming test?!
