Lizzy: Two old ladies spent the afternoon walking through Central Park. The first lady walked twice as far as the second lady. If the second lady walked four miles, what is the combined total distance, in miles, the two ladies walked?.
Me: Hmmm, let me think. I think this is the detailed solution:
The first lady walked 2 * 4 = 8 miles. In total, the two ladies walked 4 + 8 = 12 miles. Final answer: 12.
