Final answer:
The enrollment at the community college this year is 1,426 students, and Nicky's average rate of speed is 25 miles per hour.
Step-by-step explanation:
To calculate the community college enrollment for this year, which is 115% of last year's enrollment, we use the following formula:
- Current Year Enrollment = Last Year Enrollment × (Percentage Increase / 100)
Last year's enrollment was 1,240 students. Therefore, this year's enrollment is:
- 1,240 students × (115 / 100) = 1,240 students × 1.15 = 1,426 students
So, the answer is 1,426 students (option I).
For Nicky's average rate of speed, if she jogged 25 miles in one hour, her average speed is simply:
- Average Speed = Total Distance / Total Time
- 25 miles / 1 hour = 25 miles per hour
Therefore, Nicky's average speed is 25 miles per hour.
