Question

Токарь делая по 108 деталей в час, изготовил все детали за 5 ч. Если он будет делать по 60 деталей в час, то за сколько часов изготовит все детали?

Answer 1

108*5час=540 деталей
540/60 дет в час=9часов

Answer 2

Calculation of Time Required to Manufacture All Parts

To calculate the time required to manufacture all the parts, we can use the concept of proportionality. Let's assume that the number of parts manufactured is directly proportional to the time taken.

Given: - The worker can manufacture 108 parts in 1 hour. - The worker took 5 hours to manufacture all the parts.

To find: - How many hours will it take to manufacture all the parts if the worker manufactures 60 parts per hour?

Let's set up a proportion using the given information:

108 parts / 1 hour = x parts / 5 hours

To find the value of x, we can cross-multiply and solve for x:

108 * 5 = 1 * x

540 = x

Therefore, if the worker manufactures 60 parts per hour, it will take 540 hours to manufacture all the parts.
