SUMMARY
The average speed for a motorist traveling 80 km at 100 km/h and 50 km at 75 km/h is calculated using the formula for average speed, which is total distance divided by total time. The total distance is 130 km. The time taken for the first segment is 0.8 hours and for the second segment is 0.6667 hours, resulting in a total time of 1.4667 hours. Therefore, the average speed is approximately 88.6 km/h.
