document.write( "Question 1149885: the flight from Seattle to New York, with a tailwind, takes 5 hrs 15 min, and the return flight take 6 hrs 35 minutes. Since the flight time includes time to taxi from and to the gate, we should subtract 45 minutes from each time to account for this. Not shown, I was able to find out the plane was scheduled to fly a 2383 mile flight path. Assuming the plane and wind speeds are constant during both flights, estimate the wind speed, to 1 decimal place.\r
