Question 824510
Hayden is the manager of a landscaping company. He had three employees to do the entire park, Cody Kaitlin and Joseph.
Cody can complete the job in 8 hrs.
Cody rate = 1/8 job/hr
-------------------------------
kaitlin can complete the project in 6 hours.
Kaitlin rate = 1/6 job/hr
-------------------------------
Joseph is new so no one knows how it will take him.
Joseph rate = 1/x job/hr
-------------------------------------
They must all work together to complete the project. How could I explain to Hayden how long it would take Joseph working by himself?
----
Equation:
rate + rate + rate = together rate
1/8 + 1/6 + 1/x = together rate
---
Note: You did not post the together time.  You need it
to solve for Joseph's time.
