Based on the scheduled departure and arrival timings across all stations from terminal station A to terminal station F:
- Bus P: Departs A at 6:00 PM and arrives at F at 4:00 AM covering 200 km.
- Bus Q: Departs F at 7:00 PM and arrives at A at 7:00 AM covering 300 km.
What is the absolute difference between the average speeds of Bus P and Bus Q (in km/h)?
Show answer & explanation
Bus P takes 10 hours for 200 km, averaging 20 km/h. Bus Q takes 12 hours for 300 km, averaging 25 km/h. The absolute difference is 5 km/h.
Step-by-step Derivation:
Step 1: Calculate Bus P's travel time from 6:00 PM to 4:00 AM = 10 hours.
Step 2: Average speed of Bus P = 200 km / 10 h = 20 km/h.
Step 3: Calculate Bus Q's travel time from 7:00 PM to 7:00 AM = 12 hours.
Step 4: Average speed of Bus Q = 300 km / 12 h = 25 km/h.
Step 5: Absolute difference = |25 - 20| = 5 km/h.
