Question

Один станок работал 3 часа, изготавливая каждый час 1200 деталей. Менее мощный станок работал 4 часа, изготавливая по 890 деталей в час. Сколько всего деталей изготовили эти станки?

Answer 1

7160 изготовили эти станки деталей

Answer 2

1) 1200×3=3600(д) 1 станок.
2) 890×4=3560(д) 2 станок.
3) 3600+3560=7160(д) всего.
Ответ: 7160 деталей всего изготовили эти станки.

Answer 3

Total Number of Parts Produced by the Machines

The first machine worked for 3 hours and produced 1200 parts per hour, while the less powerful machine worked for 4 hours and produced 890 parts per hour. To find the total number of parts produced by these machines, we can use the following calculations:

Total parts produced by the first machine: 3 hours * 1200 parts/hour = 3600 parts

Total parts produced by the less powerful machine: 4 hours * 890 parts/hour = 3560 parts

Calculation of Total Parts Produced

To find the total number of parts produced by both machines, we can add the total parts produced by each machine:

3600 parts + 3560 parts = 7160 parts

Therefore, the total number of parts produced by these machines is 7160 parts.
