John visits three different countries.  He stays in the first country for 2 weeks and he spends twice as long in each of the other two countries.  How much time does he spend on the trip?
##Solution## He spends 2*2=<<2*2=4>>4 weeks in the other two countries
So he spends 2*4=<<2*4=8>>8 weeks in those countries combined
That means he is gone for 2+8=<<2+8=10>>10 weeks
