Problem Analysis

To solve this problem, we need to find out how many parts the turner needs to produce in the remaining 4 hours of the 8-hour workday. We are given that the turner has already produced 80 parts in the first 4 hours. We can use this information to calculate the number of parts the turner needs to produce per hour in the remaining 4 hours.

Solution

To find out how many parts the turner needs to produce per hour in the remaining 4 hours, we can use the following formula:

Number of parts per hour = (Total number of parts - Number of parts produced in the first 4 hours) / Remaining hours

Let's substitute the given values into the formula:

Number of parts per hour = (189 - 80) / 4

Simplifying the equation:

Number of parts per hour = 109 / 4

Calculating the result:

Number of parts per hour = 27.25

Therefore, the turner needs to produce approximately 27.25 parts per hour in the remaining 4 hours.

Answer

The turner needs to produce approximately 27.25 parts per hour in the remaining 4 hours.
