    Answer: after 1.8 hours, they would be 306 miles apart.

    Step-by-step explanation:

    Let t represent the time it will take for the two trains to be 306 miles apart. It means that after t hour, both trains would have covered a total of 306 miles.

    Distance = speed * time

    The eastbound train travels at 75 miles per hour. It means that the distance travelled by the eastbound train after t hours is 75t miles.

    The westbound train travels at 95 miles per hour. It means that the distance travelled by the westbound train after t hours is 95t miles.

    Since the total distance covered after t hours is 306 miles, it means that

    75t + 95t = 306

    170t = 306

    t = 306/170

    t = 1.8
