Bob can groom a horse in 2 hours. Eddie can do it in 1 1/2 hours. How long will it take to groom one horse if they work together?
----------------------------
Bob DATA:
time = 2 hr/job ; rate = 1/2 job/hr
--------------------------------------
Eddie DATA:
time = 3/2 hr/job ; rate = 2/3 job/hr
-------------------------------------
Together DATA:
time = x hr/job ; rate = 1/x job/hr
==========================================
Equation:
rate + rate = together rate
1/2 + 2/3 = 1/x
The least common multiple of the denominators is 6x.
Multiply thru by 6x to get:
3x + 4x = 6
7x = 6
x = 6/7 hr. (time required for them to do the job together)
================================================================
