Question

light travels 300,000,000 m/s, and one year has approximately 32,000,000 seconds. a light year is the distance light travels in one year. state the speed in m/s, using scientific notation. 9 x 10^0 m/s 7 x 10^15 m/s 3 x 10^8 m/s

Explanation:

Step1: Escribir 300000000 en notación científica

Para escribir un número en notación científica, se escribe como $a\times10^{n}$, donde $1\leq a < 10$ y $n$ es un entero.
Para 300000000, $a = 3$ y $n = 8$ ya que $300000000=3\times100000000 = 3\times10^{8}$.

Answer:

C. $3\times10^{8}\text{ m/s}$
