    If you know the miles per hour it should be easy. You would make a table showing each hours. So knowing that each hour one move 30 miles and the other 23. So at 2 hours one should be 60 miles out and the other 46 miles out. Now with those two numbers subtract them and you'll end up with 14 miles difference which gives you your answer. In 2 hours they will be 14 miles apart. Each hour keep adding the original number. Ex: 1 hour 30 miles, 2 hours 60 miles, 3 hours 90 miles, etc.
