Average Speed =    Total distance travelled 
                                -------------------------------
                                     Total time taken 
                          
                          =           120 + 120
                                --------------------------
                                (120/40) + (120/30)
                          
                           =       240
                                --------------
                                   3 + 4

                           =     240 / 7
                      
                           =   34.2 KMPH
