To determine the order of the trails from longest to shortest, we need to evaluate each trail's length:
- Trail A: 6,815 miles
- Trail B: 6,15 miles (which seems incomplete; let's assume it's a typo for 6.15 miles)
- Trail C: 6,23 miles (this also seems incomplete; let's assume it's a typo for 6.23 miles)
Based on this understanding, the proper lengths seem to be:
- Trail A: 6,815 miles (which is the longest)
- Trail B: 6.15 miles
- Trail C: 6.23 miles
Now we can rank the trails:
- Trail A: 6,815 miles
- Trail C: 6.23 miles
- Trail B: 6.15 miles
So the order from longest to shortest is:
A, C, B
Since none of the answer choices exactly match, if we assume Trail B is indeed shorter than Trail C based on the conditions provided, the closest option for long to short trails would be:
C, A, B (if C is considered before A based on it being smaller).
But correcting for that confusion, the ideal ranking based on clear understanding should be A, C, B without completion issues.
Please confirm or clarify the exact numbers for precise ordering.
