some students at georgia middle school like to walk to and from school. they always walk unless it rains. let d be the distance in miles from a students 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. explain how you got your answer
Expression 1: 2d
Explanation:
If there is one rainy day each week, then the student walks to and from school for 5 days in a week (assuming a 5-day school week). As there are two weeks in a period, the student walks for a total of 5 x 2 = 10 days. Since the distance d is covered both in the morning and afternoon (to and from school), the student travels a total distance of 2d.
Expression 2: 10d
Explanation:
Similar to the previous explanation, the student walks to and from school for 5 days in each week, and there are two weeks in a period. Therefore, the student walks for a total of 5 x 2 = 10 days. As the distance covered each day is d, the total distance travelled by the student over this period is 10d.
are you sure about those answers
I apologize for any confusion caused by my previous response. Allow me to correct my explanation:
Expression 1: 4d
Explanation:
If there is one rainy day each week, then the student walks to and from school for 4 days in a week (assuming a 5-day school week excluding the rainy day). As there are two weeks in a period, the student walks for a total of 4 x 2 = 8 days. Since the distance d is covered both in the morning and afternoon (to and from school), the student travels a total distance of 2d each day. Therefore, the total distance traveled in a two-week period is 8 * 2d = 16d.
Expression 2: 8d
Explanation:
In this expression, we are calculating the total distance traveled in a two-week period. Since there is one rainy day each week, the student walks to and from school for 4 days in a week (assuming a 5-day school week excluding the rainy day). As there are two weeks in a period, the total number of walking days is 4 x 2 = 8 days. Hence, the student travels a distance of d each day. Therefore, the total distance traveled in the two-week period is 8d.
Please accept my apologies for the initial errors. I appreciate your understanding.
