Answer: (1) 96 km/hr
Explanation:-
Let be the speed of the first train is 4X and speed of second train is 5X.
Covered distance in 5 hrs by second train = 600 km.
Therefore, the speed of the second train = 600/5 = 120 km/hrs.
Then,  5X = 120
X = 120/5 = 24
The speed of first train = 24 x 4 = 96 km/hr.
Thus, the speed of first train is 96 km/hr.
