Question

Фродо с друзьями под предводительством Гэндальфа вышли из Шира. Путешествие в трактир «Гарцующий пони», в котором заночевали хоббиты и маг, проходило с разной средней скоростью — пока компания не наткнулась на назгула, дело шло быстрее, а после этой встречи бодрый дух друзей поугас, и они пошли медленнее на 4 км/ч. В целом расстояние до трактира составляло 14 км, которое было преодолено за 4 часа, причём первая и вторая части пути заняли одно и то же время. С какой скоростью происходило движение до встречи с назгулом? Ответ: км/ч.

To find the speed at which Frodo and his friends were traveling before encountering the Nazgul, we can set up an equation.

Let's denote the speed before encountering the Nazgul as 'x' km/h and the reduced speed after encountering them as 'x - 4' km/h.

The total distance to the inn is 14 km, and it was covered in 4 hours.

Now, let's consider the two parts of the journey:

1. The first part of the journey was at 'x' km/h, and it took 't' hours.
2. The second part of the journey was at 'x - 4' km/h, and it also took 't' hours.

The equation for the first part of the journey is: Distance = Speed × Time 14 km = x km/h × t hours

The equation for the second part of the journey is: Distance = Speed × Time 14 km = (x - 4) km/h × t hours

Now, we know that the total time for the journey is 4 hours, so we can write another equation: t + t = 4 hours

Simplify this equation: 2t = 4 t = 2 hours

Now, we can use this value of 't' to find 'x' in the first equation: 14 km = x km/h × 2 hours

x = 14 km / 2 hours x = 7 km/h

So, the speed of their movement before encountering the Nazgul was 7 km/h.
