Final answer:
The train journey will be 2.175 centimeters on the map with a scale of 1 cm = 200 miles.
Step-by-step explanation:
To find the distance on the map, we need to use the scale of the map. Since the scale is 1 cm = 200 miles, we can set up a proportion to find the length in centimeters. Let x represent the length in centimeters:
1 cm / 200 miles = x cm / 435 miles
Multiplying both sides by 435 and dividing by 200, we get:
x cm = (1 cm / 200 miles) * 435 miles = 2.175 cm
Therefore, the train journey will be 2.175 centimeters on the map with a scale of 1 cm = 200 miles.
