add up the distances traveled:
65(14) + 75x = 1960
Hmmm. x=14, indicating they left at the same time. ??
One train left the station and traveled toward its destination at a speed of 65 miles per hour. Later, another train left the station traveling in the opposite direction of the first train, it was going at a speed of 75 miles per hour. After the first train had traveled for 14 hours it was 1960 miles apart from the second train. How long did the second train travel?
