Answer 2

Problem Analysis

We are given that a worker produced 180 parts in 3 hours, while their apprentice produced 120 parts in the same amount of time. We need to determine how many more parts the worker produced than the apprentice in 1 hour.

Solution

To find the number of parts produced by the worker in 1 hour, we can divide the total number of parts produced by the worker (180) by the total number of hours worked (3). Similarly, to find the number of parts produced by the apprentice in 1 hour, we can divide the total number of parts produced by the apprentice (120) by the total number of hours worked (3).

Let's calculate the number of parts produced by the worker and the apprentice in 1 hour.

Calculation

Number of parts produced by the worker in 1 hour: 180 parts / 3 hours = 60 parts/hour Number of parts produced by the apprentice in 1 hour: 120 parts / 3 hours = 40 parts/hour To find the difference in the number of parts produced by the worker and the apprentice in 1 hour, we subtract the number of parts produced by the apprentice from the number of parts produced by the worker:

60 parts/hour - 40 parts/hour = 20 parts/hour

Therefore, the worker produced 20 parts more than the apprentice in 1 hour.

Answer

The worker produced 20 parts more than the apprentice in 1 hour.
