betsy travel on a bus for 21 miles to school. if betsy travels for a full week (7 days). how many total miles did she travel ? Use a drawing and distributive property to solve.
She goes to school 7 days a week? Are you sure?
21 * 7 = ?
It says "full week," so I guess it would be 7.
A school week is usually 5 days.
Yes, but the word "full" stands out to me, though that part of the question is kind of vague.
To find the total distance Betsy traveled in one week, we need to multiply the number of miles she traveled in a day by the number of days in a week.
Given that Betsy travels 21 miles each day, we can represent this using the distributive property as follows:
21 miles/day × 7 days/week
To represent this visually, we can draw a rectangle to represent the total distance Betsy traveled in one day.
```
+-------------------+
| |
| 21 miles |
| |
+-------------------+
```
Next, we multiply the length of the rectangle by the number of days in a week.
Total Distance = Rectangle Length × Number of Days
Total Distance = (21 miles/day) × 7 days/week
To use the distributive property, we can consider the 7 days as the sum of two parts: 6 days + 1 day.
Total Distance = (21 miles/day) × (6 days + 1 day)
= (21 miles/day) × 6 days + (21 miles/day) × 1 day
Now, we can distribute the 21 miles/day to each part.
Total Distance = 21 miles/day × 6 days + 21 miles/day × 1 day
= 126 miles + 21 miles
Finally, we can add the two parts together to find the total distance.
Total Distance = 126 miles + 21 miles
= 147 miles
Therefore, Betsy traveled a total of 147 miles in one week.
