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.
