<PRE><B>Question 313741</B>
pam can build a house in 11 2/3 months and jerry can build a house in 8 3/4 months. if they work together, how long would it take to build the house working together.
----
Pam DATA:
time = 35/3 months/job ; rate = 3/35 job/month
----
Jerry DATA:
time = 35/4 months/job ; rate = 4/35 job/month
-------------
Together DATA: 
time = x months/job ; rate = 1/x job/month
-----------------------------------------------
Equation:
rate + rate = together rate
3/35 + 4/35 = 1/x
---
7/35 = 1/x
x = 35/7 = 5 months (time for them to do the job together)
