Answer :
Average speed = (total distance) / (total time)
Average speed = (192 km) / (8 hours) = 24 km per hour .
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
thus, time for trip = 8/2 = 4 hours.
Speed = distance / time
= 96/4 = 24 km/h
Thus, his average speed was 24 km/h
