Final answer:
Chandler ran a total of 38.75 miles over 10 days, running 3 1/2 miles each day for the first 5 days and 4 1/4 miles each day for the next 5 days.
Step-by-step explanation:
To calculate the total distance Chandler ran over the 10 days, we need to separate the calculations into two parts: the first 5 days and the next 5 days. For the first 5 days, Chandler ran 3 1/2 miles each day. For the next 5 days, she ran 4 1/4 miles each day.
Total distance for the first 5 days: 3 1/2 miles/day * 5 days = 17 1/2 (or 17.5) miles.
Total distance for the next 5 days: 4 1/4 miles/day * 5 days = 21 1/4 (or 21.25) miles.
We then add both totals together to find the overall total distance: 17.5 miles + 21.25 miles = 38.75 miles.
So, Chandler ran a total of 38.75 miles over the course of 10 days.
