Question 971873: A carpenter can do a job in two hours. His assistant can do the same job in three hours. How long would it take them to do the job together? Answer by anand429(138) (Show Source):
You can put this solution on YOUR website! Carpenter's rate of work = 1/2 units per hour
Assistant's rate of work = 1/3 units per hour
Their combined rate of work = units per hour
= units per hour
So, time required to do the job together

= hours
