Answer:
The missing value is 1/60.
Step-by-step explanation:
Given,
The time taken by Marie to work alone = 60 days,
Since,
[tex]\text{Work done in one day}=\frac{1}{\text{Time taken in days}}[/tex]
Thus, the work done by Marie in one day = [tex]\frac{1}{60}[/tex],
Hence, the rate of Marie = 1/60 per day,
Which is the missing value in the table.
