Question 1
A passenger travels from Miami to Denver via Chicago. The minimum layover at Chicago is **90 minutes**.
**Flights Miami -> Chicago:**
- F1-1: Dep 5:00 AM, Arr 6:55 AM
- F1-2: Dep 8:00 AM, Arr 9:55 AM
- F1-3: Dep 11:00 AM, Arr 12:55 PM
**Flights Chicago -> Denver:**
- F2-1: Dep 10:30 AM, Arr 1:23 PM
- F2-2: Dep 12:30 PM, Arr 3:23 PM
- F2-3: Dep 2:30 PM, Arr 5:23 PM
What is the minimum total elapsed time for the journey from Miami to Denver?
1. Timeline Approach & Constraint Application (Minimum Layover: 90 min):
The fastest total time is found by checking all 9 combinations and ensuring the layover time (F2 Dep Time - F1 Arr Time) is at least the minimum required.
2. Optimal Path Calculation:
The minimum elapsed time of 383 minutes is achieved by combining F1-3 (Arr: 12:55 PM) and F2-3 (Dep: 2:30 PM, Arr: 5:23 PM).
Total Elapsed Time = Final Arrival Time - Initial Departure Time.
3. Final Answer: The minimum elapsed time is 6 hours and 23 minutes.
