Question

6. A plane flying the 3458-mile trip from New York City to London has a 50-mph tailwind. The flight’s point of no return is the point at which the flight time required to return to New York is the same as the time required to continue to London. If the speed of the plane in still air is 600 mph, how far is New York from the point of no return?
