Question

На одном станке за 7 ч сделали 728 деталей, а на другом за 9 ч на 235 деталей больше. На каком станке изготавливали в час больше деталей? На сколько?

Answer 1

728/7=104 - на 1 станке

728+235=963 деталей на 2 станке

963/9=107 - на 2 станке

На 2 станке изготавливали в час больше деталей

107-104=3

На 3 детали больше

Answer 2

728+235=963(дет.)на 2-ом станке за 9 ч

728:7=104(дет)-на 1-ом станке за 1 ч
 963:9=107(дет)-на 2 ом станке в 1 ч
107-104= на 3 дет больше

Answer 3

Calculating Production Rates on Different Machines

To determine which machine produced more parts per hour and by how much, we can calculate the production rates for each machine.

Let's denote: - Machine 1: Produced 728 parts in 7 hours - Machine 2: Produced 728 + 235 = 963 parts in 9 hours

Production Rate Calculation

Machine 1: - Production rate = Total parts / Total time - Production rate for Machine 1 = 728 / 7 = 104 parts per hour

Machine 2: - Production rate = Total parts / Total time - Production rate for Machine 2 = 963 / 9 = 107 parts per hour

Conclusion

Machine 2 produced more parts per hour, with a production rate of 107 parts per hour compared to Machine 1's production rate of 104 parts per hour. Therefore, Machine 2 produced 3 parts per hour more than Machine 1.
