Math word Problem

Jamie and Pat volunteered to paint the hall in the E wing. If it would take Jamie 10 hours to paint the hall alone, and take Pat 5 hours to paint the hall alone, how long will it take them to paint the hall if they work together?

Susan N.

Jamie can do 1/10 the hall in one hour. 
Pat can do 1/5 the hall in one hour
The total work both can do together is 1/10+1/5= 3/10 the hall.
In order to finish the hall, they both need to work for 1/(3/10)= 3.33 hours.
