The polarized glasses contain a special filter that blocks the glares and the hazes while driving through the sun or looking at the water, which makes your eyes more comfortable and makes you see better.

Answer:
Distance of galaxy 1 = 681.82 Million light years.
Distance of galaxy 2 = 909.09 Million light years
Distance of galaxy 3 = 1136.36 Million light years.
Explanation:
Given that Hubble constant is 22km/s/Mly
Galaxy 1 is speed away from us is 15000km/s
Galaxy 2 is speed away from us is 20000km/s
Galaxy 3 is speed away from us is 25000km/s
We have to find distance to each galaxy from Hubbles law.
According to<em> Hubbles law</em> , when galaxies move away from each other the velocity with which they recede ie the red shift in spectra of distant galaxies is proportional to the distance.
Distance=Velocity/Hubble constant
Distance of galaxy 1 = = 681.82 Million light years.
Distance of galaxy 2 = = 909.09 Million light years.
Distance of galaxy 3 = = 1136.36 Million light years.
The formula for acceleration, or average acceleration, is a=(vf-vi) divided by (tf-ti) .
a= Acceleration (or average acceleration
vf= Final Velocity
vi= Initial Velocity
tf= Final Time
ti= Initial Time
