Question 86681: an airplane flew 450miles from miami to tallahassee in 1.5hrs less time than it took to fly 1,200miles from to newark.if the plane few at the same rate on both trips,find the rate of the airplane. Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! 450/(x-1.5)=1200/x now cross multiply
1200(x-1.5)=450x
1200x-1800=450x
1200x-450x=1800
750x=1800
x=1800/750
x=2.4 hours for the time of the flight.
1200/2.4=500 miles per hour for the speed of the plane.
