если взять, например, королева елизавета ii, то она не имеет права принимать решения и законы, а законы принимает премьер-министр.
быть королевой, значит выполнять множество формальностей, чтить традиции, все время махать и улыбаться на каждодневных выходах в мир. у их семьи множество ограничений во внешнем виде, запрещается ярко и выразительно краситься, носить определённых цветов одежды, краситься в цвет лака, который не выделяется. много правил и запретов. даже денег у них собственных нет. все, что они покупают, четко прослеживается, а потому покупать, все что захочется нельзя. да и деньги их, это всего лишь налоги с граждан. но зато тебе теперь не надо думать о том, как бы заработать себе на жизнь.
пусть весь путь равен s, а скорость первого автомобилиста х. получаем уравнение
s s / 2 s / 2
= +
x x - 15 90
сократив на s, получаем
1 1 1
- =
х 2 * х - 30 180
2 * х - 30 - х 1
=
х * (2 * х - 30) 180
2 * х² - 30 * х = 180 * х -5400
2 * х² - 210 * х + 5400 = 0
это уравнение имеет 2 корня
х₁ = 45 х₂ = 60
поскольку по условию х > 54, то первый автомобиль ехал со скоростью
60 км/ч
