18. An intelligent alien living on a planet in the solar system orbiting Alpha Centauri, the nearest star system to our Solar System in the Milky Way Galaxy, receives radio signals from Earth traveling at 186,421 miles/hour. The signal asks if the Alien likes McDonald Burgers. How long, in years, would it take for an Earthling to receive the answer back, Yes! (The distance from Earth to Alpha Centauri = 4.367 light years away, 1 light year 6.0 x 10" miles, and 1 year 365.2422 days)
