Question 832500: Kurt can do a job in 8 hours and Johnny can do it in 6 hours. What part of the job can they do by working together for 2 hours? For x hours? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 2/8+2/6=
6/24+8/24
14/24=7/12 of the job done in 2 hours
7/12x=2
x=24/7
1/8+1/6=1/x
x=24/7 3 3/7 hours to complete the job
x/6+x/8=
(4x+3x)/24=7x/24 of the job is done in x hours
