    Why without calculus? 17 and 18 year olds studying maths would generally be expected to at least know how to differentiate, and that the derivative will be zero at a maximum or minimum, which is all that's required here. Further, the comments below the article seem to agree that differentiation was part of the curriculum.

    so you can't solve it without Calc

    don't waste my time...
