Question

Задача: Улицу длиной 1 км 250 м, шириной 24 м покрыли асфальтом. На каждые 100 кв.м расходовали 3 т 900 кг асфальта. Сколько всего тонн астфальта израсходовали?

Answer 1

1)250*24=30000(кв.м)S улицы
2)30000:100=300(раз) по 100кв.м
3)300*3900=1170000кг(1170тонн) асфальта израсходовали

Answer 2

Calculation of Asphalt Consumption

To calculate the total amount of asphalt used to cover the street, we need to find the area of the street and then multiply it by the asphalt consumption rate.

Given: - Length of the street: 1 km 250 m - Width of the street: 24 m - Asphalt consumption rate: 3 t 900 kg per 100 sq. m

Calculating the Area of the Street

To find the area of the street, we multiply its length by its width.

Length of the street = 1 km 250 m = 1250 m Width of the street = 24 m

Area of the street = Length × Width Area of the street = 1250 m × 24 m = 30,000 sq. m

Calculating the Total Asphalt Consumption

To calculate the total asphalt consumption, we need to multiply the area of the street by the asphalt consumption rate.

Asphalt consumption rate = 3 t 900 kg per 100 sq. m Area of the street = 30,000 sq. m

Total asphalt consumption = (Area of the street ÷ 100) × Asphalt consumption rate

Total asphalt consumption = (30,000 sq. m ÷ 100) × (3 t 900 kg per 100 sq. m)

Calculating the total asphalt consumption:

Total asphalt consumption = (300 × 3 t 900 kg) Total asphalt consumption = 11,700 kg

Answer:

The total amount of asphalt used to cover the street is 11,700 kilograms.
