Question

Решите задачу Одна поливная машина истратила за 5 минут 270 л воды, а другая 468 л за 9 мин. У какой машины производительность труда больше и на сколько?решать действиями

Answer 1

1) 270:5=54 - 1 машина
2)468:9=52 - 2 машина
3)54-52=2 - разница
Ответ: 1 машина, на 2 л.

Answer 2

270:5=54 л за одну минуту 1я машина
468:9=52 л за одну минуту 2я машина
54-52=2 производительность первой машины больше

Answer 3

Problem Analysis

We are given two watering machines, and we need to determine which machine has a higher work productivity and by how much. To solve this problem, we will compare the amount of water each machine uses in a given time period.

Given Information

- Machine 1 uses 270 liters of water in 5 minutes. - Machine 2 uses 468 liters of water in 9 minutes.

Calculating Work Productivity

To compare the work productivity of the two machines, we need to calculate the amount of water used per minute for each machine.

For Machine 1: - Water used in 1 minute = 270 liters / 5 minutes = 54 liters/minute.

For Machine 2: - Water used in 1 minute = 468 liters / 9 minutes = 52 liters/minute.

Conclusion

Comparing the work productivity of the two machines, we find that Machine 1 has a higher work productivity, using 54 liters of water per minute, while Machine 2 uses 52 liters of water per minute. Therefore, Machine 1 has a higher work productivity by 2 liters per minute.
