Question 861354: I need explanation and solution:
Rustam can paint a wall in 1 hour and Anvar can paint the same wall in 2 hours. How long would it take Rustam and Anvar to paint this wall if they work together? Found 2 solutions by mananth, richwmiller:Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Rustam can paint in 1 hour
so he does 1 job in 1 hour
Anwar takes 2 hours
so he does 1/2 job in 1 hour
together they do 1+1/2 of the job in 1 hour
3/2 of the job in 1 hour
so for 1 job they together take 2/3 hours
