For the past month, Ms. Smith recorded the number of days she went to work each week and the number of gas stations she drove by during those days. How many gas stations does she drive by each day?
To find out how many gas stations Ms. Smith drives by each day, we need to calculate the average number of gas stations she drives by per week and then divide that by the number of days she goes to work each week.
Let's assume she goes to work 5 days a week.
Let's say she drove by a total of X gas stations in the past month.
Let Y be the total number of days she went to work in the past month.
Since she goes to work 5 days a week, she went to work for a total of 4 weeks in the past month. Therefore, Y = 4 weeks * 5 days/week = 20 days.
So, the average number of gas stations she drives by each day is X gas stations / 20 days = X/20.
Therefore, Ms. Smith drives by X/20 gas stations each day.
