Answer:
It means the Judy's rate to complete the puzzle is [tex]\frac{1}{3}.[/tex]
Step-by-step explanation:
If Judy completes a puzzle by herself, it takes her 3 hours.
Working with Sal, it only takes them 2 hours
We have been given the rates of time taken by Judy and Sal to complete a puzzle.
We can see from our given table that Sal's rate is r. We are told that Judy completes a puzzle by herself, it takes her 3 hours. working with Sal, it only takes them 2 hours.
It is given that Judy completes a puzzle by herself, it takes her 3 hours.
so part of puzzle completed by Judy in one hour would be[tex]\frac{1}{3}[/tex]
Therefore, the part of puzzle completed by Judy in one hour is [tex]\frac{1}{3}.[/tex]
