Final answer:
To extend the 5-kilometer course, it needs to be extended by 4 kilometers.
Step-by-step explanation:
To find out how much further the course needs to be extended, we need to add up the distances provided in yards and convert the total to kilometers.
Given:
- Main street to 6th Ave: 781 yards
- 6th Ave to Pleasant Road: 1,250 yards
- Pleasant Road to City Park: 275 yards
- Route through City Park: 2,337 yards
- City Park to Main Street: 725 yards
We add up these distances: 781 + 1,250 + 275 + 2,337 + 725 = 4,368 yards.
Next, we convert this total to kilometers. Since there are 1,094 yards in 1 kilometer, we divide the total yards by 1,094: 4,368 / 1,094 = 4 kilometers (rounded to the nearest kilometer).
Therefore, the course needs to be extended by 4 kilometers.
