Question

Масса одного метра рельса равна 32 кг. Сколько понадобится железнодорожных вагонов грузоподъёмностью 60 т, чтобы перевезти все рельсы, необходимые для постройки одноколейной железной дороги длиной 180 км ?

Answer 1

180 км =180000м 180000*32=5760000 5760000/60=96000 железнодорожных вагонов понадобится для перевозки железной дороги длиной 180 км

Answer 2

Calculating the Number of Railway Cars Needed to Transport Rails

To calculate the number of railway cars needed to transport the rails for a 180 km long single-track railway, we can use the given information that the mass of one meter of rail is 32 kg and the railway cars have a carrying capacity of 60 tons.

Calculation

First, let's convert the mass of one meter of rail from kilograms to tons: 1. Convert the mass of one meter of rail from kilograms to tons: - 32 kg = 0.032 tons.

Next, we can calculate the total mass of the rails needed for the 180 km long single-track railway: 2. Calculate the total mass of the rails needed: - Total mass = (32 kg/m) * (1000 m/km) * (180 km) = 5,760,000 kg = 5760 tons.

Now, we can determine the number of railway cars needed to transport the total mass of the rails: 3. Calculate the number of railway cars needed: - Number of railway cars = Total mass / Carrying capacity per car - Number of railway cars = 5760 tons / 60 tons/car = 96 railway cars.

Answer

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