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 hours?

Answers

Answer 1

Answer: Average speed = (total distance) / (total time)

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

Answer 2

Answer: 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
