Suppose you are traveling by train to visit a friend who lives 275 away. how long will the triptake moveing at a constant speed. how long would it take the train to travel 385 miles?

If you were going at a speed of 55 miles an hour (greatest common factor) then it'll take 5 hours to go 275 miles, and 7 hours to go 385. 

If none of those work for you then please supply me with the rate the train is moving at so I am able to give you the correct time.

The correct answer is this:
Pi= 3.14159
3.14159+ 6,909.04= 6,912.18159
Hope this helped have a great day :-)
