My question is: Every Monday to Friday morning, Alice walks 10 miles through a large grass field to get to school. To avoid the hot afternoon sun on her way home, she walks 12 miles through a forest. When she gets home on Friday, how many miles will she have walked that week? Your thoughts:
On Monday the total number of miles Alice walks to and from school is 10 + 12 = 22 miles. For the other 4 days, from Tuesday to Friday, she walks an additional 4 * 22 = 88 miles. The total number of miles she will have walked by Friday 22 + 88 = 110 miles. The final answer: 110.
