The average distance between galaxies is about one million light years. There are roughly 100 billion galaxies in the observable universe. Another, often-used unit of distance is the parsec. One parsec is approximately 3.26 light-years.
The combined speed of the plane and the wind is 249.35 km/h.
<h3>
Relative speed</h3>
The relative speed of the plane due to speed of the wind is calculated as follows;
Let the direction of the plane be horizontal direction.
<h3>Speed of the wind</h3>
The speed of the wind is calculated as follows;
<h3>Combined speed</h3>
The combined speed of the plane and the wind is calculated as follows;
V = 275 km/h - 25.65 km/h
V = 249.35 km/h
Thus, the combined speed of the plane and the wind is 249.35 km/h.
