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 km/s, using scientific notation. 3 x 10^12 km/s 3 x 10^5 km/s

Explanation:

Step1: Convert metros a kilómetros

Sabemos que 1 km = 1000 m = 10³ m. Entonces, para convertir 300000000 m/s a km/s, dividimos entre 1000.
$300000000\div1000 = 300000$ km/s

Step2: Escribir en notación científica

La notación científica es de la forma $a\times10^{n}$, donde $1\leq a<10$ y $n$ es un entero. Para 300000, $a = 3$ y $n = 5$. Así, 300000 km/s = $3\times10^{5}$ km/s

Answer:

$3\times10^{5}$ km/s
