Question 52417
Patrice DATA:
time=10 hr/job ; rate= 1/10 job/hr.
------------
Together DATA:
time=6 hr/job ; rate = 1/6 job/hr.
---------------
April DATA:
time= x hr/job ; rate = 1/x job/hr.
--------------
EQUATION:
Patrice rate + April Rate = Together rate
1/10 + 1/x = 1/6
Multiply thru by 30x to get:
3x + 30 = 5x
2x=30
x=15
April would take 15 hours to do the job.
Cheers,
