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...

1. Use the law of cosines. 180 -53 -51=76° d²=800² + 700² -2*800*700cos76°; d≈926.8 miles 2. Θ=arctan(76/52)≈ 55.6 90 -55.6=34.4° N 34.4° W

Change the navigational directions to trigonometry directions. 90 - 100= -10° and 90 - 70=20° 440cos(-10°)i + 440sin20°j + 50cos20°i + 50sin20°j =480.3i + -59.3j magnitude= √(480.3² + -59.3²)≈483.9 mph direction= arctan(-59.3/480.3)≈ -7.04° or a bearing of 90+7.04= 97.04°

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...

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