Lizzy: Hazel walked 2 kilometers in the first hour. If she walked twice as far in the second hour, how far did she walk for 2 hours?.
Me: Hmmm, let me think. I think this is the detailed solution:
Hazel walked 2 x 2 = 4 kilometers in the second hour. So, she walked 2 + 4 = 6 kilometers for 2 hours. Final answer: 6.
