HEY DEAR ... ✌

Let the speed of the train be x km/hr and speed of car be y km/hr

Ved travels 120 km by train, the distance covered by car 600-120 = 480 km

Now, time taken to cover 120 km by train = 120/xhr

And time taken to cover 480 km by car = 480/y 

Total time taken to travel 600 km = 120/x + 480/y = 8 hr (i)

Similarly 

200/x + 400/y = 8hr. 20minute = 8(20/60) (ii)

solve (i) and (ii) 

we get 

x = 60 km/hr and y = 80 km/hr

Hope, it helps ... ✌
