Question

Масса одного метра рельса равна 32 кг сколько понадобиться железгодорожных вагонов грузободъемностью 60т.чтобы перевезти все рельсы необходимые для постройки одноколейной железной дороги длиной 180км

Answer 1

180 км=180 000 м.1)180 000*32*2 =11 520 000 (кг)=11 520 т-масса рельс.2)11 520 : 60= 192 вагона понадобится

Answer 2

180км=180000м
для укладки 180км пути необходимо 180000*2=360000 рельсов.
значит для перевозки понадобится 32*360000:60000=32*6=192 вагона.

Answer 3

Calculation of Railroad Cars Needed to Transport Rails

To calculate the number of railroad cars needed to transport the rails for the construction of a single-track railway, we can use the given information:

- The mass of one meter of rail is 32 kg. - The required length of the railway is 180 km. - The carrying capacity of each railroad car is 60 tons.

Calculation Steps

1. Calculate the Total Mass of the Rails - The total mass of the rails can be calculated by multiplying the mass of one meter of rail by the total length of the railway. - Total mass of rails = Mass of one meter of rail * Total length of railway

2. Convert the Total Mass to Tons - Since the carrying capacity of each railroad car is given in tons, we need to convert the total mass of the rails from kilograms to tons.

3. Determine the Number of Railroad Cars Needed - Finally, we can divide the total mass of the rails (in tons) by the carrying capacity of each railroad car to find out how many railroad cars are needed to transport the rails.

Let's proceed with the calculations.

Calculation

1. Calculate the Total Mass of the Rails - Total mass of rails = 32 kg/m * 180,000 m - Total mass of rails = 5,760,000 kg

2. Convert the Total Mass to Tons - Total mass of rails = 5,760,000 kg = 5,760,000 kg / 1000 kg/ton - Total mass of rails = 5,760 tons

3. Determine the Number of Railroad Cars Needed - Number of railroad cars needed = Total mass of rails / Carrying capacity of each railroad car - Number of railroad cars needed = 5,760 tons / 60 tons/car - Number of railroad cars needed = 96 railroad cars

Conclusion

To transport all the rails necessary for the construction of a single-track railway with a length of 180 km, it would require 96 railroad cars with a carrying capacity of 60 tons each.
