If Cody can work in 8 hours, and Kaitlyn in 6, how much time will it take them if they work together?
-----------
Cody rate:: 1/8 job/hr
Kait rate:: 1/6 job/hr
---
Together rate:: 1/x
-------
Equation::
rate + rate = together rate
1/8 + 1/6 = 1/x
--------------------
6x + 8x = 8*6
------
14x = 48
-----
x = 24/7 = 3 3/7 hrs (time to do the job together)
---------------------
