Final answer:
After reeling in the line at a consistent rate of 0.5 feet per second for 5 seconds, the fisherman would have 22.5 feet of line out.
Step-by-step explanation:
The student is dealing with a physics problem that involves linear motion at a constant rate.
The fishing line is reeled in at a rate of 0.5 feet per second.
To calculate how much line is out after 5 seconds, one would subtract the amount of line reeled in from the original length of the line out.
After 5 seconds, at a rate of 0.5 feet per second, the fisherman would have reeled in 2.5 feet of line (5 seconds * 0.5 feet/second), making the new length of line out 22.5 feet (25 feet - 2.5 feet).
