Question: Cheryl got angry with her sister and decided to run away from home. She walked 2 miles every hour for 3 hours. Then she got homesick and walked back home. How many miles did Cheryl walk in total? Think carefully first, then make a decision:
Cheryl walked 2 miles x 3 hours = 6 miles. Once Cheryl was 6 miles away, she walked back home, another 6 miles, so she walked 6 + 6 = 12 miles. So the answer is 12.
