SUMMARY
The average speed for a round trip of 297.2 km, where the first half is traveled at 84.6 km/hr and the second half at 50.6 km/hr, is calculated by determining the total time taken for the trip, including a 1.2-hour lunch break. The correct formula to use is average speed = total distance / total time. The total time is derived from the individual segments of the trip, resulting in an average speed of approximately 52.1 km/hr.
