Question 34128: Two jets leave the same airfield at the same time, traveling in opposite directions. One jet travels 80 miles faster than the other. In 8 hours the planes are 7200 miles apart. What is the speed of each plane?
Answer by Paul(988) (Show Source): You can put this solution on YOUR website!
One jet's speed = 80+x
another jet'sspeed = x
Equation:
8(x+x+80)=7200
16x+160=7200
16x=7040
x=440
440+80=520
Hence, one jet's speed is 440 and another jet's speed is 520mph.
