Abus travels 126km in 3 hrs                         (Speed = distance travelled / time taken)
                    Abus  = 126/3  = 42 
train travels 315 km = 5 hrs
                    Train  = 315/5  = 63 
The ratio of Abus : Train = 42 : 63  =  6 :9
                                           = 2 : 3

it is totally wrong

Bus travels 126 km in 3 hrs
therefore speed = 126/3
42km/ hr

bus travels 315 km in 5 hrs
therefore speed = 315/5
63 km/hr

ratio of speed = 42 : 63
2 : 3

hope this helps u
