A Plane TripLogic puzzles require you to think. You will have to be logical in your reasoning.Two identical airplanes (Plane A and Plane B) make the round-trip flight from Miami to Las Vegas on different days. They both use the exact same route, have the same layover time in Las Vegas and flight conditions are the same, save one: Plane A experiences no winds on the flight, and Plane B experiences a constant wind that gives it a headwind (flying against the wind) going to Las Vegas, and a tailwind (flying with the wind) back to Miami. If both airplanes maintain the same airspeed (speed relative to the wind) the entire flight, which airplane will take longer to complete the round-trip? Why?

I felt that it was a much more intriguing puzzle to solve logically (to think of the why) and only use math as a proof. If it fell under the math category, it just becomes routine number crunching excercise. I appreciate the comments!
