The speed of light is approximately 1 86 * 10% miles per second. X The time it takes for a beam of light to travel from the Sun to Earth is found by dividing the distance between the Sun and Earth by the speed of light. Find the amount of time it takes for a beam of light from the Sun to reach Earth. Show all work and express your answer in minutes. Explain or show how to use the numbers in scientific notation to calculate the difference in the distance from Jupiter to the Sun and the distance from Mars to the Sun. Then find the differences and express your answer in scientific notation. 1 • Explain or show how to find the number of miles light will travel in 1/2 minute.
