**Reiny**, Tuesday, February 19, 2008 at 1:38pmdraw two triangles, one that has an angle of 71.5º and another with an angle of 51.6º

lets find the base in each one, call the first one x, the other one y

tan71.5 = 28000/x

x = 28000/tan71.5 = 9368.67

tan51.6 = 2800/y

y = 22192.53

So the horizontal distance travelled in 73 seconds is y-x = 12823.86

speed = distance/time = 12823.86/73

= 128.34 m/second

BTW, that airplane must be a spacecraft to fly at a height of 28 km, lol
