Explanation:
To find the percentage of the trip that Keith's wife drove, we can use the following formula:
Percentage = (Part / Whole) * 100
Where:
- Part is the distance driven by Keith's wife.
- Whole is the total distance of the trip (500 miles).
Keith drove 259 miles of the 500-mile trip. To find how much his wife drove, we subtract Keith's distance from the total distance:
Distance driven by Keith's wife = Total distance - Distance driven by Keith
Distance driven by Keith's wife = 500 miles - 259 miles = 241 miles
Now, let's calculate the percentage of the trip that Keith's wife drove:
Percentage = (241 miles / 500 miles) * 100 ≈ 48.2%
Therefore, Keith's wife drove approximately 48.2% of the trip. The correct answer is (B) 48.2%.
