The table lists 21 options for one-way air travel from Milwaukee, Wisconsin, to Seattle, Washington, on March 20, 2011. Each option is either a nonstop flight or a flight involving one or more stops and possible transfer to a different flight. For each option, the originating flight is the first flight in the sequence (or the single flight if it is nonstop), and the corresponding airline is the originating airline; the base price is the price quoted for the option, and the total price is the base price plus all applicable taxes and fees. The total trip time is the elapsed time from scheduled departure of the originating flight to scheduled arrival at the final destination.
For each of the following statements, select Yes if the statement is true based on the information provided; otherwise select No.

Hi Shivani,
Let me try to help you.
Statement 3 asks you whether Air Tran was the originating airline for the "only" direct flight to Milwaukee; given that the mean speed of each flight in the list was roughly the same.
Let us simplify this, we know \(Mean speed = \frac{Total distance covered in the trip}{Total time taken for the trip}\) Hence, Total time taken ∝ Total distance covered.
The only direct flight to Milwaukee will have the "least" total distance traveled as all other connecting flights will need to cover more distances, traveling via other airports. And from the above proportionality, we know that ⬇️distance traveled => ⬇️Total time taken.
Thus we need to check if Air Tran is the originating airline for the flight with the least total travel time in the given table. If it does answer is Yes else it's No. Sorting the table by Total Trip time(hours) we DO see that Air Tran takes the least time, and thus, is the only direct flight to Milwaukee. So it's a Yes.
I hope this helps you!

Speeds are almost the same for all planes ( we are considering ideal situation - we cannot use external extrapolations in gmat ).
If the speeds are same for all planes then, all planes who have a stoppage will take more time than the direct flight takes . Hence Only the one with shortest flight time is the non-stop flight .
