Answer: The equation that represents the situation is d = k/p, where k is a constant.
This equation states that the number of days taken to complete the work (d) is inversely proportional to the number of people working on the job (p).
Given that 10 people work on the job and it takes them d days to complete it, we can substitute these values into the equation:
d = k/10
We don't know the value of k, so we can't find out the number of days it takes with 10 people working.
