Stefan left school and traveled toward his friend's house. Eugene left two hours later traveling at 40 km/h in an effort to catch up to stefan. after traveling for three hours eugene finally caught up. what was stefan's average speed?
Since it was 2 hours, you multiple 40 times two since it's 40 km per HOur. So you get 80 km per hour. Since was 40 km per hour add 80+40 you get 120. Since the over all hours tracked was 5 I would divide 120/5 = 24
