Question 393653
 Three people can pick all the apples from five trees in five hours. How long will it take five people?
-----------------
time to pick all the apples is directly related to # of trees and inversely 
related to # of people.
----
time = kT/p
---
Solve for "k" using "Three people can pick all the apples from five trees in five hours."
5 = k5/3
k = 3
---
Equation for this problem:
time = 3T/p
----
Problem: How long will it take five people?
t = 3*5/5
---
Ans: 3 hrs
