Both are needed to receive full credit. Use ^ symbol for exponents (10^8 for 108) A. The speed of light is 3.00x108 m/s. What is this speed in km/hr?B, A light year is approximately 9.46x1012 km. What is the diameter of our galaxy in km?C. As of now, the highest speed obtained by a human piloted vehicle is around 40,000 km/hr (achieved by the Apollo 10 spacecraft re-entering the Earth’s atmosphere). How long would it take for a spacecraft traveling at this speed to travel from one edge of the galaxy 100,000 light years across to the other side? Give your answer in hours and in days (1 day = 24 hours).
