Answer: 85 miles per hour
Step-by-step explanation:
We know that the formula to calculate speed is given by :-
[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]
Given: The distance traveled by Aaron in train = 680 miles
The time taken by train = 8 hours
Then, [tex]\text{Speed}=\dfrac{680}{8}=85\text{ miles per hour}[/tex]
Hence, the speed of the train=85 miles per hour
