Question 511296
If a job can be completed by 2 workers in 10 days, then what is the number of workers needed to complete the job in 5 days?

-----
Days and # of workers are indirectly related:
w = k/d
---
Solve for "k" using "2 workers in 10 days":
2 = k/10
k = 20
-----
Equation: 
w = 20/d
-----------
what is the number of workers needed to complete the job in 5 days?
w = 20/5
# of workers = 4
