Question 913229: Ed can do a job in 4 days. When Ed and Maymay work together, it would take them 2 1/3 days. How long would the job take Maymay to do the job alone? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Ed can do a job in 4 days.
so he does 1/4 of the job in 1 day
When Ed and Maymay work together, it would take them 2 1/3 days.
so they together do 3/7 of the job in 1 day
Maymay will do 3/7 - 1/4 of the job in 1 day
=(12-7)/28
=5/28 of the job in 1 day
so Mayamy will take 28/5 days to complete the job alone
5.6 days
