31. We apply Eq. 37-36 for the Doppler shift in wavelength: ∆λ λ = v c where v is the recessional speed of the galaxy. We use Hubble’s law to find the recessional speed: v = Hr , where r is the distance to the galaxy and H is the Hubble constant () 3 m sly 21.8 10 . × Thus, ( ) 38 6 21.8 10 m/s ly 2.40 10 ly 5.23 10 m/s v
