Question 1040128: an airplane flew for 8 hours at an airspeed of x miles per (mph), and for 7 more hours at 325 mph. If the average airspeed for the entire flight was 350 mph, which of the following equations could be used to find x
x + 325 = 2(350)
x + 7(325)= 15(350)
8x - 7(325) = 350
8x + 7(325)=2(350)
8x + 7(325)= 15(350) Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! .
Total miles traveled=15 hours x average 350 mph
First 8 hours = 8x
Last 7 hours = 7(325mph)
.
Total =first eight plus last seven
8x + 7(325)= 15(350)
.
