Here's the full question:
Train A, traveling at 200 mph, leaves station A at 1 pm. Train B, traveling at 300 mph, leaves station B at 3 pm. Both stations are directly across from each other and x miles away. The trains meet at 4 pm. What is x?
At 4 pm, train A has been traveling for 3 hours.
3 hours × 200 mph = 600 miles
At that time, train B has been traveling for 1 hour.
1 hour × 300 mph = 300 miles
Answer:
x = 900 (miles)

Are you missing something.
If train a leaves at 1 pm at 200 mph. At 4 pm, it would have traveled 3 hours. So 200 mph * 3 hr = 600 miles. So x us 600 mikes from train A starting point.
