Final answer:
Jacinta will run 450 miles in 25 days.
Step-by-step explanation:
To find the answer, we can first calculate the average number of miles Jacinta runs per day. We divide the total miles by the number of days: 306 miles ÷ 17 days = 18 miles per day.
Next, we can calculate the number of miles Jacinta will run in 25 days by multiplying the average number of miles per day by the number of days: 18 miles/day × 25 days = 450 miles.
Therefore, Jacinta will run 450 miles in 25 days, so the correct answer is Option B) 350 miles.
