Question

Light travels 3 x 10^5 kilometers in one second. How far does it travel in 6.7 seconds? Write your answer in scientific notation.

Answer 1

We can write the question as this equation :
$\frac{1}{3*10^5} = \frac{6.7}{x}$
Where x is the distance in kilometers, so to find x:
X= 6.7*3*10^5 = 20.1*10^5 km
