Question

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

Answer 1

1) 108х5=540-деталей изготовил всего

2) 540:60=9 - за столько часов он изготовит детали, если по 60 в час 

Answer 2

1.108*5=540(деталей)-сделал за 5 час

2.540:60=9(час)-сделает все детали 

Answer 3

Problem Analysis

A lathe operator is manufacturing 108 parts in 5 hours. We need to determine how many hours it will take for the operator to manufacture the same number of parts if they produce at a rate of 60 parts per hour.

Solution

To find the number of hours it will take to manufacture 108 parts at a rate of 60 parts per hour, we can set up a proportion:

108 parts / 5 hours = x parts / y hours

To solve for y, we can cross-multiply and then divide:

108 * y = 5 * x

y = (5 * x) / 108

Let's calculate the value of y.

Calculation

Using the given values, we can substitute x = 60 into the equation:

y = (5 * 60) / 108

Simplifying the equation:

y = 300 / 108

Calculating the value of y:

y ≈ 2.7778 hours

Therefore, if the operator produces at a rate of 60 parts per hour, it will take approximately 2.7778 hours to manufacture all 108 parts.

Answer

If the operator produces at a rate of 60 parts per hour, it will take approximately 2.7778 hours to manufacture all 108 parts.
