| π§ REASONING SUMMARY | |
| ββββββββββββββββββββ | |
| Compute distance for each segment (speed Γ time), add them for total distance, then divide total distance by total time to get average speed. | |
| β FINAL ANSWER | |
| ββββββββββββββββββββ | |
| 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. |
