🧠 REASONING SUMMARY
────────────────────
Compute distance for each segment (speed Γ— time), add them for total distance, then divide total distance by total time to get average speed.
βœ… FINAL ANSWER
────────────────────
Distance = (60 mph Γ— 2.5 h) + (40 mph Γ— 1.5 h) = 150 + 60 = 210 miles.
Total time = 2.5 + 1.5 = 4.0 hours.
Average speed = 210 Γ· 4.0 = 52.5 mph.
