Question

масса одного метра рельса равна 32кг.Ско-ко понадоб. железнодорожных вагонов грузоподъемностью 60т ,чтобы перевезти все рельсы,необходимые для постройки одноколейной железной дороги длиной 180км?

Answer 1

1 м рельса - 32 кг
Грузоподъёмность - 60т
Длина дороги - 180 км
Решение:

 

1км=1000м

180*2=360км=360 000м

1т=1000кг

360 000*32=11 520 000кг=11 520т

11 520/60=192 вагонов понадобится

Ответ: понадобится 192 железнодорожных вагонов

Answer 2

Calculating the Number of Railway Cars Needed

To calculate the number of railway cars needed to transport all the rails required for the construction of a single-track railway line, we can use the given information about the mass of one meter of rail and the carrying capacity of the railway cars.

Given: - Mass of one meter of rail = 32 kg - Carrying capacity of railway cars = 60 tons - Length of the railway line = 180 km

Calculation Steps

1. Convert the length of the railway line from kilometers to meters: - 180 km = 180,000 meters

2. Calculate the total mass of the rails needed for the entire railway line: - Total mass of rails = Mass of one meter of rail * Length of the railway line

3. Determine the number of railway cars needed to transport the total mass of the rails: - Number of railway cars = Total mass of rails / Carrying capacity of each railway car

Solution

Step 1: Convert Length to Meters - Length of the railway line = 180 km = 180,000 meters

Step 2: Calculate Total Mass of Rails - Total mass of rails = 32 kg/m * 180,000 m - Total mass of rails = 5,760,000 kg

Step 3: Determine Number of Railway Cars - Number of railway cars = 5,760,000 kg / (60,000 kg/car) - Number of railway cars = 96 railway cars

Therefore, 96 railway cars with a carrying capacity of 60 tons each would be needed to transport all the rails required for the construction of a single-track railway line with a length of 180 km.
