Explanation :
It is given that,
Velocity of plane, v = 1100 mi/h
Proxima Centauri is a red dwarf star. Its distance from Earth to Proxima Centauri is 4.243 light year.
Or we can say that the distance between Earth and Proxima Centauri is,
[tex]d=2.49\times 10^{13}\ miles[/tex]
We know that, time [tex]t=\dfrac{d}{s}[/tex]
[tex]t=\dfrac{2.49\times 10^{13}\ miles}{1100\ miles/h}[/tex]
[tex]t=0.22\times 10^{11}\ h[/tex]
or
t = 2.5 years ( approx )
Hence, this is the required solution.
