Students like to walk to and from school. They always walk unless it rains. Let d be the distance in miles from a student's home to the school. Write two different expressions that represent how far a student travels by walking in a two week period if there is one rainy day each week
Expression 1: 13d
Explanation: Since there is one rainy day each week, the student will walk for 13 days in a two-week period (14 days - 1 rainy day each week). Therefore, the expression can be written as 13d, where d represents the distance from the student's home to the school.
Expression 2: 2d
Explanation: In a two-week period, the student will walk to and from school 13 times (since there is one rainy day each week). This means the student will walk a total of 26 times, which is equivalent to walking 2 times each day for 13 days. Therefore, the expression can be written as 2d.
