Nathan and Matt plan to paint a house. If Nathan works alone, it will take
10 days. If Matt works alone, it will take 15 days. How many days will it
take to finish the job if they work together?

Answer :

Nathan= 1/10 of the job per day

Matt= 1/15 of the job per day

3/30 + 2/30. =5/30

1/(5/30) = 30/5. Or 6 days for both working together.
