Expression 1: 12d
Explanation: Since there is one rainy day each week, the student would walk to and from school for 6 days in a week. In a two-week period, the student would walk for 6 days x 2 weeks = 12 days. The distance traveled by walking for each of these 12 days is d miles. Therefore, the total distance traveled by walking in a two-week period is 12d miles.
Expression 2: 6d
Explanation: Similar to the previous expression, the student would walk to and from school for 6 days in a week. In a two-week period, the student would walk for 6 days x 2 weeks = 12 days. However, since the question specifies that there is one rainy day each week, the student would not walk on these rainy days. Hence, the total distance traveled by walking in a two-week period would be for 6 days x 2 weeks - 2 rainy days = 12 days - 2 days = 10 days. The distance traveled by walking for each of these 10 days is d miles. Therefore, the total distance traveled by walking in a two-week period is 10d miles.
What is the 2 Expression for this Question 2: (6.PAR.6.3) - Some of the students at Georgia Middle School like to walk to and from school. They always walk unless it rains.
