he went 96 km and came back same distance so
total distance is 96 + 96 = 192 km
time taken was 8 hrs..
as speed is distance/time,
so, speed = 192/8
speed would be 24 km/h

The whole distance traveled from Perry to Medford was
192 kms (96 one way x 2). Therefore, if the round trip took a total of 8 hours, then Pedro's average speed is equal to
Distance Traveled/Hours Traveled
192/8 = 24 km/hr

Round trip took 8 hours and the distance is 96 x 2 = 192 kilometers. So, the average speed is 192/8 = 24 km/h
