1. ### How how in the air do I have to fly my paper airplane to simulate (by scale) a jetliner at 35,000 feet?

Your paper aeroplane is 3 inches high or 7.62cm. I presume you mean to compare that with the distance from the ground to the top of a Boeing 737 fuselage, which is about 6 meters. That would be a scale of 1 to 600 / 7.62 = about 1 to 80. On that basis...

8. ### Vectors help?

The calculation depends a bit on how you found the plane's speed. If you found the rectangular coordinates of the plane after 1 hour, you can use an inverse trig function to find the direction. If you used a vector calculator to add the vectors, put the...

10. ### An airplane has just enough fuel for a 6 hour flight how far can it fly round trip in which during the first leg of the trip (check details)?

round trip is 2x miles time for first leg = x miles Ā· (1 hour)/(235 miles) = x/235 hours time for second leg = x miles Ā· (1 hour)/(190 miles) = x/190 hours x/235 + x/190 = 6 38x + 47x = 53580 85x = 53580 2x = 1260.705 miles
