Question

Туристы прошли свой маршрут за два дня в первый день они прошли до привала семь двадцатых маршрута ещё 15 км после привала второй день до привала две пятых маршрута и после привала 10 км чему равна длина маршрута

Answer 1

7/12+2/5=(7*5+2*12)/60=(35+24)/60=59/60 маршрута
остальное составило 15+10=25 км что составляло 1-59/60=1/60 маршрута
значит весь маршрут 25*60=1500 км
1500*7/12+15=890км
1500*2/5+10=610км
890+610=1500км

Answer 2

I can answer your question in detail. Tourists walked their route in two days. On the first day they walked to the halt seven twentieths of the route and another 15 km after the halt. On the second day to the halt two fifths of the route and after the halt 10 km. What is the length of the route?

Let x be the length of the route in kilometers. Then, according to the given information, we can write the following equation:

$$\frac{7}{20}x + 15 + \frac{2}{5}x + 10 = x$$

Solving for x, we get:

$$\frac{7}{20}x + \frac{2}{5}x = x - 25$$

$$\frac{9}{20}x = x - 25$$

$$x - \frac{9}{20}x = 25$$

$$\frac{11}{20}x = 25$$

$$x = \frac{25}{11} \times 20$$

$$x = \frac{500}{11}$$

Therefore, the length of the route is $$\frac{500}{11}$$ kilometers, which is approximately 45.45 kilometers. You can check the answer by substituting x with this value in the original equation.
