Answer:
Ground speed is 61.67 km /h.
Step-by-step explanation:
Ground speed of aircraft is obtained b the sum of aircraft speed minus the current speed and direction.
For this the given formula is
81-27 cos (255 - 81 )
53.704 km/h
27 sin ( 225 - 81 ) = 2.822 km /h
so ground speed = ![\sqrt{(53.704 ^2 + 2.822)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%2853.704%20%5E2%20%2B%202.822%29%5E2%7D)
= 61.67 km /h

Answer:
0.45 / ![\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D)
Step-by-step explanation:
![(-\frac{1}{2} )(\frac{3}{5} )+\frac{3}{2} -\frac{3}{5} (\frac{5}{4} )](https://tex.z-dn.net/?f=%28-%5Cfrac%7B1%7D%7B2%7D%20%29%28%5Cfrac%7B3%7D%7B5%7D%20%29%2B%5Cfrac%7B3%7D%7B2%7D%20-%5Cfrac%7B3%7D%7B5%7D%20%28%5Cfrac%7B5%7D%7B4%7D%20%29)
![=\frac{9}{20} / 0.45](https://tex.z-dn.net/?f=%3D%5Cfrac%7B9%7D%7B20%7D%20%2F%200.45)
