Some people see many ways to the solution to the same problem at once. Espescially in exams, it's good to use the fastest way to save time.
Here is how I would have solved your problem in an exam.
Since A and B are traveling toward each other in constant velocities, then their traveled distance as time goes on add up until the sum reaches 1118 miles. So the distance traveled by A or B is proportional to the speeds they travel.
So, from where A started, A and B meets at [(348)/(348 +168)] *1118 = 754 miles.
