.

Let "t" be the time traveled by the train.


Then the time traveled by the bus was (6-t) hours.


Next, you write the total distance equation


    70t + 60*(6-t) = 395.


Finally, you solve this equation


    t = %28395+-+60%2A6%29%2F%2870-60%29 = 3.5.


ANSWER.  3.5 hours by the train.

Solved.
