Question

Мастер изготовил за 6 часов 360 деталей а его ученик на этот же объем работы потратил в 2 раза больше времени. За какое время можно сделать 360 деталей если мастер и ученик будут работать вместе

Answer 1

Ответ:

360:6=60 деталей в час мастер

6*2=12 часов ученику понадобилось на 360 деталей

360:12=30 деталей в час ученик

30+60=90 деталей в час ученик и мастер

360:90=4 часа мастер и ученик вместе

Answer 2

Calculating Time to Make 360 Parts

To calculate the time it would take for the master and the apprentice to make 360 parts working together, we can use the information provided about their individual rates of production.

Given: - The master made 360 parts in 6 hours. - The apprentice took twice as long to make the same amount of parts.

We can calculate the apprentice's time to make 360 parts: - The apprentice took 6 hours * 2 = 12 hours to make 360 parts.

Time Taken Working Together

When the master and the apprentice work together, their combined rate of production is the sum of their individual rates. Therefore, the combined rate of production is: - Master's rate: 360 parts / 6 hours = 60 parts per hour - Apprentice's rate: 360 parts / 12 hours = 30 parts per hour

The combined rate when working together is: - Combined rate: 60 parts per hour + 30 parts per hour = 90 parts per hour

To find the time it would take for the master and the apprentice to make 360 parts working together, we can use the combined rate: - Time to make 360 parts together: 360 parts / 90 parts per hour = 4 hours

Therefore, if the master and the apprentice work together, they can make 360 parts in 4 hours.
