It was 96 kilometers from Perry to Medford. David raced to Medford and idled back. If the round trip took 8 hours, what was his average speed in kilometers per hour?

Average speed = (total distance) / (total time)
Average speed = (192 km) / (8 hours) = 24 km per hour .

Time for round trip = 8 hours
thus, time for trip = 8/2 = 4 hours.
Speed = distance / time
= 96/4 = 24 km/h
Thus, his average speed was 24 km/h

David's average speed for the round trip was 24 kilometers per hour. This was calculated by dividing the total distance of 192 kilometers by the total time of 8 hours. Therefore, his average speed is 24 km/h .
