24 km/h I got this by giving a total distance of 120 km, or 60 km per leg of the trip. At 20k m/h, It would take 3 hours for the first leg. At 30 km/h, it would take 2 hours for the leg. Add the times, and you will get 5 hours. At the distance of the two legs and you get 120 km. THen, you compute 120/5. That is the average km/hour. actually it is 25 km/h anyway nice try. you were quite close.
