Question

Улица длиной 1км 250м и шириной 24м покрыли асфальтом.на каждые 100м квадратных расходовали 3 т 900 кг асфальта. сколько всего тонн асфальта израсходовали

Answer 1

Площадь покрытия асфальтом равна  1км 250м * 24 м=1250 *24 30000 кв.м. тогда количество асфальта , необходимого для покрытия улицы , исходя из условия задачи равно = 30000/100 *3,9 = 1170т
Ответ : 1170 т

Answer 2

Calculation of Asphalt Consumption

To calculate the total amount of asphalt used to cover a street that is 1 km 250 m long and 24 m wide, we need to determine the area of the street and then calculate the asphalt consumption per square meter.

The area of the street can be calculated by multiplying its length by its width:

Area of the street = Length × Width

Given that the length of the street is 1 km 250 m (or 1,250 m) and the width is 24 m, we can calculate the area as follows:

Area of the street = 1,250 m × 24 m

Now that we have the area of the street, we can calculate the asphalt consumption per square meter. According to the information provided, every 100 square meters require 3 tons 900 kg of asphalt.

To calculate the asphalt consumption per square meter, we can use the following formula:

Asphalt consumption per square meter = Total asphalt consumption / Total area

Given that every 100 square meters require 3 tons 900 kg of asphalt, we can calculate the asphalt consumption per square meter as follows:

Asphalt consumption per square meter = (3 tons 900 kg) / 100 square meters

Now, let's calculate the total amount of asphalt used to cover the street.

Calculation Steps:

1. Calculate the area of the street: - Length of the street: 1,250 m - Width of the street: 24 m - Area of the street = 1,250 m × 24 m

2. Calculate the asphalt consumption per square meter: - Asphalt consumption per 100 square meters: 3 tons 900 kg - Asphalt consumption per square meter = (3 tons 900 kg) / 100 square meters

3. Calculate the total amount of asphalt used: - Total asphalt consumption = Asphalt consumption per square meter × Area of the street

Let's perform the calculations.

Calculation:

1. Calculate the area of the street: - Length of the street: 1,250 m - Width of the street: 24 m - Area of the street = 1,250 m × 24 m = 30,000 square meters

2. Calculate the asphalt consumption per square meter: - Asphalt consumption per 100 square meters: 3 tons 900 kg - Asphalt consumption per square meter = (3 tons 900 kg) / 100 square meters = 39 kg per square meter

3. Calculate the total amount of asphalt used: - Total asphalt consumption = Asphalt consumption per square meter × Area of the street - Total asphalt consumption = 39 kg per square meter × 30,000 square meters

Therefore, the total amount of asphalt used to cover the street is 1,170,000 kg or 1,170 tons.
