Question 714830: A private jet flies the same distance in 12 hours that a commercial jet flies in 9 hours. If the speed of the commercial jet was 198mph less than 2 times the speed of the private jet, find the speed of each jet. Answer by lynnlo(4176) (Show Source):
You can put this solution on YOUR website! COMMERCIAL JET=2X-198
PRIVATE JET====SPEED=X
EQUATION:
12(X)=9(2X-198)
12X=18X-1782
2X=1782
X=891
2(891)-198=693
PRIVATE==================891MILES
COMMERIAL================693MILES
