The first train covers 60 miles between 3 and 4 pm. So at 4 pm, the trains are only 140 miles apart. Since they travel at the same rate, they will meet when they have each covered half the 140, or 70 miles. At 60 miles per hour, it takes 70 minutes to cover 70 miles. Thus they will meet at 5:10 pm.
