Understanding the Relationship
* More cows, less time: If you have more cows, it will take less time to graze the field.
* Fewer cows, more time: If you have fewer cows, it will take more time to graze the field.
Calculations
1. Calculate the work of one cow in one day:
* If 3 cows graze the field in 'x' days, one cow would take 3 times as long.
* So, one cow would take 3x days to graze the field.
2. We don't know the exact value of 'x' (the number of days for 3 cows). To find the time for one cow, we need to know how long it takes 3 cows.
Example:
Let's say it takes 3 cows 6 days to graze the field (x = 6):
* One cow would take 3 * 6 = 18 days.
In Conclusion
You can't determine how long it takes one cow to graze the field without knowing how long it takes 3 cows.
