Question

light travels 3 x 10^5 kilometers in one second. how far does it travel in 44 seconds? write your answer in scientific notation.

Explanation:

Step1: Identify the speed of light

The speed of light is $v = 3\times10^{5}$ km/s.

Step2: Use the formula $d=v\times t$

Here, $t = 44$ s. So $d=(3\times10^{5})\times44$.

Step3: Calculate the distance

$(3\times10^{5})\times44 = 3\times44\times10^{5}=132\times10^{5}$.

Step4: Convert to scientific - notation

$132\times10^{5}=1.32\times10^{2}\times10^{5}=1.32\times10^{7}$ km.

Answer:

$1.32\times10^{7}$ km
