Question

Для перевозки зерна выделили три машины. На одну из них погрузили 3 т зерна, на вторую-на 1 т больше,чем на первую, а на третью машину-в 2 раза меньше зерна, чем на вторую. Сколько зерна перевезли эти машины за три рейса? с ответом

Answer 1

3+1=4т-погрузили на вторую машину                                                                       4:2=2т- погрузили на третью машину                                                                       3+4+2=9т- погрузили на три машины всего               

Answer 2

1) 3+1=4(т) - вторая машина
2) 4:2=2(т) - третья машина
3) 3+4+2=9(т) - во всех трех машинах
4) 9*3=27(т) 
Ответ: за три рейса отвезли 27 тонн зерна.

Answer 3

Problem Analysis

We are given three machines for transporting grain. The first machine is loaded with 3 tons of grain, the second machine is loaded with 1 ton more than the first machine, and the third machine is loaded with half the amount of grain as the second machine. We need to calculate the total amount of grain transported by these machines in three trips.

Solution

To find the total amount of grain transported, we need to calculate the amount of grain loaded on each machine for each trip and then sum them up.

Let's calculate the amount of grain loaded on each machine for each trip:

Trip 1: - Machine 1: 3 tons - Machine 2: 1 ton more than Machine 1, so 3 + 1 = 4 tons - Machine 3: Half the amount of Machine 2, so 4 / 2 = 2 tons

Trip 2: - Machine 1: 3 tons - Machine 2: 1 ton more than Machine 1, so 3 + 1 = 4 tons - Machine 3: Half the amount of Machine 2, so 4 / 2 = 2 tons

Trip 3: - Machine 1: 3 tons - Machine 2: 1 ton more than Machine 1, so 3 + 1 = 4 tons - Machine 3: Half the amount of Machine 2, so 4 / 2 = 2 tons

Now, let's calculate the total amount of grain transported by summing up the amounts for each machine:

- Machine 1: 3 + 3 + 3 = 9 tons - Machine 2: 4 + 4 + 4 = 12 tons - Machine 3: 2 + 2 + 2 = 6 tons

Therefore, the three machines transported a total of 9 + 12 + 6 = 27 tons of grain in three trips.

Answer

The three machines transported a total of 27 tons of grain in three trips.
