Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Below is the solution:

distance = 475
time = 9.5 hrs

since distance and time varies directly

therefore in 9.5 hrs train travels 475 miles => In 1 hr train travels 475 / 9.5 miles = 50 miles
and in 4 hrs train travells 50*4 i.e 200 miles
