Пошаговое объяснение:

3/5 заасфальтировали, осталось 2/5 и это 8 км

8 : 2/5=8*5/2=20 (км) вся дорога

Answer 2

Calculating the Length of the Entire Road

To determine the length of the entire road, we can use a simple proportion to find the total length based on the portion that has been paved.

Given: - Portion of road paved: 3/5 - Remaining length of the road: 8 km

We can use the following proportion to find the total length of the road:

\[ \frac{{\text{Paved length}}}{{\text{Total length}}} = \frac{{3}}{{5}} \]

Calculation

Let's solve for the total length of the road using the given information:

\[ \frac{{3}}{{5}} = \frac{{\text{Paved length}}}{{\text{Total length}}} \]

We can solve for the total length by cross-multiplying:

\[ 3 \times \text{Total length} = 5 \times \text{Paved length} \]

Now, we can substitute the given values:

\[ 3 \times \text{Total length} = 5 \times 8 \, \text{km} \]

Solving for the total length:

\[ \text{Total length} = \frac{{5 \times 8 \, \text{km}}}{{3}} = \frac{{40 \, \text{km}}}{{3}} = 13.\overline{3} \, \text{km} \]

Answer

The total length of the entire road is approximately 13.3 km.
