Solution:
At 5:30 PM the distance between the train will be 621 miles.
Explanation:
We have been given that one train goes north and other train gores south. It means they are moving in opposite direction.
When two body moving in opposite directions then the relative velocity is the sum of their individual velocities.
Therefore, the relative speed is given by
[tex]v=75+63 = 138 mph[/tex]
Now, the distance between the train is 621 miles. Hence, using the relation between speed, time and distance, we have
[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}\\\\138=\frac{621}{t} \\\\t=\frac{621}{138}\\\\t=4.5[/tex]
Thus, at 5:30 PM the distance between the train will be 621 miles.
