--------------------------------
t = k*L/p
===========
Solve for "k" using "It takes 8 people 3 days to dig a ditch that is 1,000 feet long,
3 = k*1000/8
k = 24/1000
k = 0.024
-----------------
Equation:t = days
t = 0.024*L/p
---
how long will it take 4 people to dig a ditch that is 500 feet long? 0
t = 0.024*500/4
t = 12/4
t = 3 days
