Question

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

Answer 1

1)43+28=71
2)100%-71=29%
3)14.5*100% и делим на 29%=50км
ответ: 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 x kilometers.

On the first day, the tourist covered 43% of the total route, which is equal to 43% of x kilometers.

On the second day, the tourist covered 28% of the total route, which is equal to 28% of x kilometers.

On the third day, the remaining distance covered was 14.5 kilometers.

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

43% of x + 28% of x + 14.5 kilometers = x

Simplifying the equation:

0.43x + 0.28x + 14.5 kilometers = x

Combining like terms:

0.71x + 14.5 kilometers = x

Subtracting 0.71x from both sides:

14.5 kilometers = x - 0.71x

Simplifying:

14.5 kilometers = 0.29x

Dividing both sides by 0.29:

x = 14.5 kilometers / 0.29

Calculating:

x ≈ 50 kilometers

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