Question

Одна машина сортирует в час 240 кг а другая за это же время - на 50 кг меньше. Сколько килограммов зерна от обе машины за 2 часа?

Answer 1

240-50=190 кг вторая за час
250+190=440 кг обе за час
440*2=880 кг обе за 2 часа

Answer 2

240-50=190 кг сортирует вторая машина за 1 час
240+190=430 кг сортируют вместе за 1 час
430*2=860 кг сортируют вместе за 2 часа
=======================

Answer 3

Problem Analysis

We are given two machines that sort grains. One machine sorts 240 kg of grain per hour, while the other machine sorts 50 kg less in the same amount of time. We need to determine the total amount of grain sorted by both machines in 2 hours.

Solution

To find the total amount of grain sorted by both machines in 2 hours, we need to calculate the amount sorted by each machine individually and then add them together.

Let's start by calculating the amount of grain sorted by the first machine in 2 hours. Since the machine sorts 240 kg of grain per hour, in 2 hours it will sort 240 kg/hour * 2 hours = 480 kg.

Now let's calculate the amount of grain sorted by the second machine in 2 hours. We know that the second machine sorts 50 kg less than the first machine in the same amount of time. So, the second machine sorts 240 kg/hour - 50 kg/hour = 190 kg/hour. In 2 hours, it will sort 190 kg/hour * 2 hours = 380 kg.

Finally, we can find the total amount of grain sorted by both machines in 2 hours by adding the amounts sorted by each machine: 480 kg + 380 kg = 860 kg.

Therefore, both machines will sort a total of 860 kg of grain in 2 hours.

Answer

Both machines will sort a total of 860 kg of grain in 2 hours.
