Sure, let's break down the solution step-by-step to identify the best possible time to run 1.5 miles from the given choices:
First, let's convert each of the given times into seconds, since it's easier to compare them that way.
1. Option A: 15 minutes, 30 seconds
- Convert minutes to seconds: \(15 \times 60 = 900\) seconds
- Total time in seconds: \(900 + 30 = 930\) seconds
2. Option B: 13 minutes, 36 seconds
- Convert minutes to seconds: \(13 \times 60 = 780\) seconds
- Total time in seconds: \(780 + 36 = 816\) seconds
3. Option C: 9 minutes, 12 seconds
- Convert minutes to seconds: \(9 \times 60 = 540\) seconds
- Total time in seconds: \(540 + 12 = 552\) seconds
4. Option D: 10 minutes, 23 seconds
- Convert minutes to seconds: \(10 \times 60 = 600\) seconds
- Total time in seconds: \(600 + 23 = 623\) seconds
Next, we compare the total times in seconds to determine the smallest (best) time:
- Option A: 930 seconds
- Option B: 816 seconds
- Option C: 552 seconds
- Option D: 623 seconds
The smallest time among these is 552 seconds, which corresponds to Option C: 9 minutes, 12 seconds.
Therefore, the best possible time to run 1.5 miles is:
Option C: 9 minutes, 12 seconds.
