Question

Железнодорожная платформа рассчитана на груз 450 ц. В товарный вагон можгл погрузить на 170 ц меньше . Грузоподъёмность цистерны на 50 ц больше , чем у вагона. Рассчитай,какой груз может переврзти железнодорожный состав, в котором 4 платформы, 7 товарных вагонови 4 цистерны. *По правилам перевозок общая масса груза на железной дороге не должна превышать 500 т. Может ли проехать полностью загруженный товарный поез,описанный в задаче.Помогите срочно надо!!!

Answer 1

1) 450 - 170 = 280 (ц) - грузоподъёмность вагона
2) 280 + 50 = 330 (ц) - грузоподъёмность цистерны
3) 450 * 4 + 280 * 7 + 330 * 4 = 1800 + 1960 + 1320 = 5080 (ц) = 508(т) -
   это грузоподъёмность полностью загруженного товарного состава.
4) 508т больше, чем 500т
Ответ: не может полностью загруженный товарный поезд проехать по
           железной дороге.

Answer 2

Calculation of Maximum Load for the Freight Train

To calculate the maximum load the freight train can carry, we need to consider the capacity of the railway platform, the capacity of the freight wagons, and the total number of platforms, wagons, and tank cars in the train.

Given information: - Railway platform capacity: 450 tons - Capacity of a freight wagon: 170 tons less than the platform capacity - Capacity of a tank car: 50 tons more than the capacity of a wagon - Total number of platforms: 4 - Total number of freight wagons: 7 - Total number of tank cars: 4 - Maximum total load allowed on the railway: 500 tons

Calculation Steps

1. Calculate the total load capacity of the freight wagons: - Capacity of a freight wagon = 450 tons - 170 tons = 280 tons

2. Calculate the total load capacity of the tank cars: - Capacity of a tank car = 280 tons + 50 tons = 330 tons

3. Calculate the total load capacity of the entire train: - Total load capacity of the platforms = 450 tons * 4 = 1800 tons - Total load capacity of the freight wagons = 280 tons * 7 = 1960 tons - Total load capacity of the tank cars = 330 tons * 4 = 1320 tons - Total load capacity of the entire train = 1800 tons (platforms) + 1960 tons (wagons) + 1320 tons (tank cars) = 4360 tons

Conclusion

The total load capacity of the entire train, including the platforms, freight wagons, and tank cars, is 4360 tons. This exceeds the maximum total load allowed on the railway, which is 500 tons. Therefore, the fully loaded freight train described in the problem cannot pass according to the rules of railway transportation.
