stronomer David observes that a distant quasar is receding from the Earth at a speed of 0.80c. He also observes a not-as-distant galaxy to be receding from the Earth at a speed of 0.20c. How fast is the quasar receding in the frame of the galaxy? Express your answer as a fraction of c = 2.998 x 10^4 m/s.  PLEASE draw out situation/diagram.  answer should be 0.71
