ANSWER
The train is moving 82.5mi/hr
EXPLANATION
How fast the train is going is the same as the speed of the train:
The speed of the train is calculated using the formula,
[tex]Speed = \frac{distance}{time} [/tex]
[tex]Speed = \frac{330}{4} [/tex]
[tex]Speed = 82.5[/tex]
Therefore the train is moving 82.5mi/hr
