Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:
He spends 2 * 2 = 4 weeks in the other two countries. So he spends 2 * 4 = 8 weeks in those countries combined. That means he is gone for 2 + 8 = 10 weeks. Final answer: 10.
