If you are flying to a city 800 miles away, what will be the difference in flight times between flying into a 40-mph headwind and flying with a 40-mph tailwind if the plane's maximum speed with no wind is 160 mph?
assuming you actually do fly at maximum speed, and recalling that time = distance/speed,
800/(160-40) - 800/(160+40)
= 800/120 - 800/200
= 2.666 hours, or 2 hr 40 min
