Question

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

Answer 1

1) 108*5=540 (д.) - всего изготовил
2) 540/60=9 (ч)

Answer 2

Problem Analysis

We are given that a lathe operator can produce 108 parts in 1 hour and has completed all the parts in 5 hours. We need to determine how many hours it would take for the operator to produce all the parts if they were producing at a rate of 60 parts per hour.

Solution

To solve this problem, we can use the concept of proportionality. The number of parts produced is directly proportional to the time taken. We can set up a proportion to find the unknown time.

Let's denote the unknown time as x.

The proportion can be set up as follows:

108 parts / 1 hour = x parts / 60 hours

To solve for x, we can cross-multiply and solve for x:

108 * 60 = 1 * x

x = 108 * 60

Now, let's calculate the value of x:

x = 6480

Therefore, if the operator produces 60 parts per hour, it would take them 6480 hours to produce all the parts.

Answer

If the operator produces 60 parts per hour, it would take them 6480 hours to produce all the parts.
