why did u start with part c

really appreciate this

You explained this much better than the other people from similar videos that I watched. Good job!

Thank You so much!

amazing vid helped a ton

Great video sir very clear.

in c) isnt it y=14

Part d was done incorrectly, you've written the working right but you put into the calculator wrong. The answer should round to 120m

Thank you so much

I find this is NOT a very helpful method. I have a bit of an issue with the term 'correct estimate', but the process that 'transforms' advocates is FAR more useful & memorable than remembering YET ANOTHER formula that you're advocating here. The method you show invariably leads to confused students because they confuse and/or misremember the fraction in the formula you show here.

This is the one

Thanks man its the same question i got exactly i was completely clueless about part (c)

🍳thanks a lot

Exactly the question I've been stuck on and somehow found this video!! thank you its a lifesaver :)

Thank you so much, that is exceptionally considerate of you! - mikele

11 mark tough a-level question. 4 mins. Not bad :)
