Problem Analysis

We are given that a master can process 68 workpieces in an hour, while their apprentice can process 32 workpieces in the same amount of time. The master worked alone for 2 hours and then worked with the apprentice for 3 hours. We need to determine how many workpieces they processed together in 5 hours.

Solution

To solve this problem, we can break it down into two parts: the work done by the master alone and the work done by the master and the apprentice together.

# Work done by the master alone

The master worked alone for 2 hours, and we know that the master can process 68 workpieces in an hour. Therefore, the work done by the master alone is 2 hours × 68 workpieces/hour = 136 workpieces.

# Work done by the master and the apprentice together

After working alone for 2 hours, the master worked with the apprentice for 3 hours. During this time, they can process a total of 68 + 32 = 100 workpieces in an hour.

To find the total work done by the master and the apprentice together, we multiply the number of hours they worked together by the combined work rate of 100 workpieces per hour.

The total work done by the master and the apprentice together is 3 hours × 100 workpieces/hour = 300 workpieces.

# Total work done in 5 hours

To find the total work done in 5 hours, we add the work done by the master alone and the work done by the master and the apprentice together.

Total work done = Work done by the master alone + Work done by the master and the apprentice together Total work done = 136 workpieces + 300 workpieces Total work done = 436 workpieces

Therefore, the master and the apprentice processed 436 workpieces in 5 hours.

Answer

The master and the apprentice processed 436 workpieces in 5 hours.
