carmen can retile the kitchen floor in 8 hours but if joe helps her, the job will only take 3.5 hours. how long would it take joe to do the job alone? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! 1/8+1/X=1/3.5
1/X=1/3.5-1/8
1/X=(8-3.5)/(3.5*8)
1/X=4.5/28
4.5X=28
X=28/4.5
X=6.22 HOURS FOR JOE WORKING ALONE.
