Answer:
________________________________
Time taken by quasar light to reach Earth = 3 billion years
= 3 × 109 years
= 3 × 109 × 365 × 24 × 60 × 60 s
Speed of light = 3 × 108 m/s
Distance between the Earth and quasar
= (3 × 108) × (3 × 109 × 365 × 24 × 60 × 60)
= 283824 × 1020 m
= 2.8 × 1022 km

Answer: t= 3*10⁹ years
Time in seconds= 3*10⁹*365*24*60*60
= 94608000*10⁹ s
Speed = 3*10⁸m/s
Distance= speed *time
= 3*10⁸*94608000*10⁹
= 283824000*10¹⁷m
= 283824*10²⁰m
= 2.8*10²²km
