Since we're looking at alternative approaches .....

1. Find the time it takes A and B to meet by pretending that B is stationary and A is moving towards B at 348 + 168 = 516 mph.

Then the time it takes A to reach B is 1118/516 = 13/6 hours.

2. So in real life A travels (348)(13/6) = 754 miles before meeting B.

3. So A and B meet 754 miles from where A started.


4. Check: B travels (168)(13/6) = 364 miles. 754 + 364 = 1118.

Edit: Just read nikhil's reply more carefully and it says the same thing. Nikhil, try putting more line spaces etc. in your replies to improve their readability.
