Question

Масса одного м 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 нужно перевести в Метры
ну 180.000.м
180.000*32=5.760.000 кг 
5.760.000 кг нужно перевести в Тонны 
5.760.000./1000=5760 т 
5760/60=96 вагон
ответ: чтобы доставить рельсы нужно 96 вагонов

Answer 2

Calculation of the Number of Freight Cars Needed

To calculate the number of freight cars needed to transport all the rails required for a 180 km long single-track railway, we need to consider the weight of each rail and the carrying capacity of the freight cars.

Given that the weight of one rail is 32 kg and the carrying capacity of each freight car is 60 tons (60,000 kg) we can calculate the number of freight cars needed as follows:

1. Convert the weight of one rail to tons: - 32 kg = 0.032 tons

2. Calculate the total weight of all the rails needed for the railway: - Total weight of rails = weight of one rail * number of rails - Number of rails = length of railway / length of one rail - Number of rails = 180,000 m / 1 m (since the length of one rail is not provided) - Number of rails = 180,000

3. Calculate the number of freight cars needed: - Number of freight cars = total weight of rails / carrying capacity of each freight car - Number of freight cars = (0.032 tons * 180,000) / 60 tons - Number of freight cars = 96,000 / 60 - Number of freight cars = 1,600

Therefore, to transport all the rails required for a 180 km long single-track railway, it would require 1,600 freight cars with a carrying capacity of 60 tons each.

Please note that the calculation assumes that the length of one rail is 1 meter, as it is not provided in the question.
