Problem Analysis

We are given that a master can complete a task in 3 hours, which is one-third of the time it takes for their student to complete the same task. We need to determine the fraction of the task each of them completes in 1 hour, the fraction they complete together in 1 hour, and the time it takes for them to complete the entire task when working together.

Solution

Let's assume that the total work required to complete the task is represented by 1 unit.

1. Fraction of work completed by the master in 1 hour: - Since the master can complete the task in 3 hours, they complete 1/3 of the task in 1 hour.

2. Fraction of work completed by the student in 1 hour: - Since the student takes three times longer than the master to complete the task, they complete 1/9 of the task in 1 hour.

3. Fraction of work completed by both the master and the student together in 1 hour: - When working together, the master and the student complete the task in 1 hour, which means they complete 1/1 or the entire task in 1 hour.

4. Time taken to complete the entire task when working together: - Since the master and the student complete the entire task in 1 hour when working together, they will take 3 hours to complete the entire task.

Therefore, the answers to the given questions are as follows: - The master completes 1/3 of the task in 1 hour. - The student completes 1/9 of the task in 1 hour. - The master and the student together complete the entire task in 1 hour. - It will take them 3 hours to complete the entire task when working together.
