Given 
Total distance = 600 km
Consider speed of Train = x km/h
Consider speed of Car = y km/h
According to the question:
We know Time = distance/speed

Situation 1 
He takes 8 hours if he travels 120 km by train and rest by car

120/x + 480/y = 8-------(1)

Situation (2)
when he travels 200 km by train and rest by car he takes 8 hr 20 min
8 hr 20 min = 25/3 hr

200/x + 400/y = 25/3 ---------(2)

solve equation 1 and 2

you'll get x = 60
so the speed of the train = 60 km/h(option 7)
