Total distance by the car =  7 3/8 + 16 1/3  =    59/8 + 49/3
                                             =  177/24 + 329/24 =   506/24
for 2 1/2 litters  distance covered = 506/24 km
for one litters  distance covered =    506/24/5/2
                                                        = 506/24* 2/5
                                                         = 1012/120
                                                         ~  8.433km

Get first the total distance that the car have travelled
7 3/8 + 16 1/3 = 59/8 + 49/3
                      =  (177+392)/24
                      = 569/24

then divide the distance by the no. of liters
 (569/24)/(5/2)=569/60
                    = 9 29/60
                    = 9.48333333333....
