how can you know that to change into hours, we should multiply. We shouldn't multiply, we should divide it by 60. I also found another mistake u have done. that is 4.5+4.5=9000 u have written but it is 9km. Ok! u can change your mistakes

19.28571427kmph
average speed=total distance travelled /total
time taken
total distance =4.5+4.5=9km
total time=12+16=28
=28/60
=0.466666667
then
average speed=9/0.466666667
=19.28571427km/h
