An airplane that flies from New York City to Los Angeles for Speedy State Airlines flies at an average speed of 450 mph and uses an average of 0.5 gal of fuel every second.
Determine the plane's fuel efficiency, in miles per gallon, by first converting the plane's speed into miles per
second. Show your work.
