Let the speed of the train be x km/hr and the speed of the bus is y km/hr.
So according to question and using
Total distance =300 km
Mansi travels 60 km by train and 300−60=240 by bus in 4 minute,
and 100 km by train, 300−100=200 by bus, and takes 10 minutes more,
Now, let
and.
multiply (1) by 5 and (2) by 6 we get
Subtracting (3) and (4) we get
Putting the value of a in (1) we get
Now ,
Hence, the speed of the train is 60 km/hr and the speed of the bus is 80 km/hr.
