Question

На завод отправлено 3600 т угля в вагонах, по 60 т в каждом из, и столько же угля в вагонах, по 90 т каждом каких вагонов потребовалось больше и сколько больше?

Answer 1

1) 3600т : 60т = 60в
2) 3600т : 90т =40в
3) 60 - 40= 20в
Ответ:  60т ваг. больше на 20 шт.

Answer 2

Calculating the Number of Wagons

To calculate the number of wagons required for the shipment of coal, we can use the given information.

The total amount of coal sent to the factory is 3600 tons. It was sent in two types of wagons: 1. Wagons carrying 60 tons of coal each. 2. Wagons carrying 90 tons of coal each.

Let's denote the number of wagons carrying 60 tons of coal as x and the number of wagons carrying 90 tons of coal as y.

We can set up the following equations based on the given information: 1. 60x + 90y = 3600 (total amount of coal sent) 2. x = y (the number of wagons carrying 60 tons is equal to the number of wagons carrying 90 tons)

We can solve these equations to find the values of x and y.

Solving the Equations

Using the given equations, we can solve for the values of x and y.

First, we can substitute the value of x from the second equation into the first equation: 60x + 90x = 3600 150x = 3600 x = 24

Now that we have the value of x, we can find the value of y using the second equation: y = x y = 24

Calculating the Difference

Now that we have found the values of x and y, we can calculate the difference in the number of wagons required for each type of wagon.

The number of wagons required for 60 tons of coal is 24, and the number of wagons required for 90 tons of coal is also 24. Therefore, no type of wagon required more than the other.

In conclusion, both types of wagons required the same number, which is 24 wagons each.
