Question

В первый день турист прошёл 43% всего маршрута, во второй день-28%, а в третий-оставшиеся 14,5 км.Сколько километров составляла длина всего маршрута?

Answer 1

В первые два дня турист прошёл 71% пути
значит в третий день он прошёл 29% пути, что составляет 14,5 км
весь путь составляет (14,5·100)/29=50 км

Answer 2

Calculation of the Total Length of the Route

To calculate the total length of the route, we can use the information provided about the percentage of the route covered on each day.

Let's assume the total length of the route is represented by the variable x.

According to the information given: - On the first day, the tourist covered 43% of the total route. - On the second day, the tourist covered 28% of the total route. - On the third day, the remaining distance was 14.5 km.

To calculate the total length of the route, we can set up the following equation:

0.43x + 0.28x + 14.5 = x

Simplifying the equation:

0.71x + 14.5 = x

Subtracting 0.71x from both sides:

14.5 = 0.29x

Dividing both sides by 0.29:

x = 14.5 / 0.29

Calculating the value of x:

x = 50

Therefore, the total length of the route is 50 kilometers.
