Step-by-step explanation:

The redshift phenomenon is a manifestation of the Doppler effect - the faster the motion, the larger the shift of the frequency. Therefore, the larger the redshift, the greater the distance to the observed galaxy. The exact relation between the redshift and distance follows from the cosmological model of the universe.
