To compare Dale's and Chan's distances, we can use division. Here's how you can compare them:
1. Dale ran 5 miles, and Chan ran 2.5 miles.
2. To compare, divide the distance Dale ran by the distance Chan ran:
5 miles / 2.5 miles = 2
3. This calculation shows that Dale ran 2 times the distance Chan ran.
4. Therefore, Dale's distance (5 miles) is twice Chan's distance (2.5 miles).
In conclusion, Dale ran twice the distance Chan ran.
