Final answer:
The journey from Geneva to Milan takes 2 hours.
Step-by-step explanation:
To calculate the time it takes for the train to travel from Geneva to Milan, we can use the formula:
Time = Distance / Speed
Given that the distance between Geneva and Milan is 200 miles, and the train's speed is 100 miles per hour, we can substitute these values into the formula:
Time = 200 miles / 100 miles per hour
Time = 2 hours
Therefore, the journey from Geneva to Milan takes 2 hours.
