Question

Одна бригада может расфасовать 450000 конфет за 10 часов, а вторая за 15 часов.За сколько часов они расфасуют такое же количество конфет, работая вместе с той же производительностью

Answer 1

Примем всю работу за 1

1) 1:15=1/15

222) 1:10=1/10

3) 1/15+1/10=5/30=1/6

4444) 1:1/6=6часов

Answer 2

Ответ:

6 часов

Пошаговое объяснение:

450000:10 =45000 конфет расфасуют 1 бригада за 1 ч

450000:15=30000 конфет расфасовывает 2 бригада за 1 ч

45000+30000=75000 конфет вместе за 1 час

450000:75000=6 ч нужно для расфасовки работая вместе

Answer 3

Calculating Combined Work Efficiency

To find out how long it will take for both brigades to pack the same amount of candy working together at the same efficiency, we can use the concept of combined work.

Let's calculate it step by step.

Step 1: Calculate the Individual Rates

- The first brigade can pack 450,000 candies in 10 hours. - The second brigade can pack 450,000 candies in 15 hours.

To find their individual rates, we can use the formula: Rate = Work / Time.

- First brigade's rate: 450,000 candies / 10 hours = 45,000 candies per hour. - Second brigade's rate: 450,000 candies / 15 hours = 30,000 candies per hour.

Step 2: Calculate Combined Work Efficiency

To find the combined work efficiency, we add their individual rates: 45,000 candies per hour + 30,000 candies per hour = 75,000 candies per hour.

Step 3: Calculate the Time Taken Working Together

Now, we can use the combined work efficiency to find out how long it will take for both brigades to pack the same amount of candy.

Using the formula: Time = Work / Rate.

- Time taken working together: 450,000 candies / 75,000 candies per hour = 6 hours.

Therefore, working together at the same efficiency, both brigades will pack the same amount of candy in 6 hours.
