Question

В 100 одинаковых вагонах можно перевезти 6000 тонн угля. В трех таких вагонах помещается столько угля, сколько в двух большегрузных вагонах. Сколько тонн угля в одном бльшегркзном вагоне?

Answer 1

1) 6000 т : 100 = 60 т/вагон 
2) 3 * 60 = 180 тонн в трех вагонах
3) 180 : 2 = 90 тонн в одном большегрузном

Answer 2

1)6000:100=60т провозится в 1 вагоне
2)3*60=180т помещается в 3х вагонах
3)180:2=90т помещается в 1 большегрузном вагоне

Answer 3

Problem Analysis

To solve this problem, we need to determine the weight of coal in one large freight car. We are given that 100 identical freight cars can transport 6000 tons of coal, and that three of these freight cars can hold the same amount of coal as two large freight cars.

Solution

Let's assume that the weight of coal in one large freight car is x tons.

According to the given information, 100 identical freight cars can transport 6000 tons of coal. This means that the weight of coal in one identical freight car is 6000 tons divided by 100, which is 60 tons per freight car.

We are also given that three identical freight cars can hold the same amount of coal as two large freight cars. This means that the weight of coal in three identical freight cars is equal to the weight of coal in two large freight cars.

Using this information, we can set up the following equation:

3 * 60 tons = 2 * x tons

Simplifying the equation, we have:

180 tons = 2x tons

Dividing both sides of the equation by 2, we get:

90 tons = x

Therefore, the weight of coal in one large freight car is 90 tons.

Answer

One large freight car can hold 90 tons of coal.
