Answer 3

Calculation of Chairs Repaired by the Master and Apprentice

To determine the number of chairs that the master and apprentice can repair together in 5 hours, we need to calculate the repair rate of each individual and then add them together.

According to the information provided, the master can repair 18 chairs in 3 hours, while the apprentice can repair 9 chairs in the same amount of time.

To find the repair rate per hour for each individual, we can divide the number of chairs repaired by the number of hours worked.

The master's repair rate per hour is 6 chairs (18 chairs / 3 hours), and the apprentice's repair rate per hour is 3 chairs (9 chairs / 3 hours).

Calculation of Chairs Repaired Together in 5 Hours

To calculate the number of chairs that the master and apprentice can repair together in 5 hours, we need to add their individual repair rates and multiply the sum by 5.

The combined repair rate per hour for the master and apprentice is 9 chairs (6 chairs + 3 chairs).

Multiplying the combined repair rate per hour by 5, we find that the master and apprentice can repair 45 chairs together in 5 hours.

Therefore, the master and apprentice can repair 45 chairs together in 5 hours.

Answer:

The master can repair 18 chairs in 3 hours, and the apprentice can repair 9 chairs in the same amount of time. Together, they can repair 45 chairs in 5 hours.
