###Human: James decides to try and collect rare artifacts in the field.  He spends 6 months researching before going on a 2-year-long expedition for his first find.  The second artifact takes 3 times as long for the research and discovery.  How long did it take him to find both?, ### Assistant: The research took 6/12=.5 years
So it took 2+.5=2.5 years for the first artifact
It takes 2.5*3=7.5 years for the second
So in total it took 2.5+7.5=10 years to find both 
 So the answer is :  10
