Answer:
[tex]d=2.77\cdot 10^6\ Km[/tex]
Explanation:
Speed
The speed is calculated as the ratio of the distance d by the time t:
[tex]\displaystyle v=\frac{d}{t}[/tex]
If we need to calculate the distance, the equation is solved for d:
d=v*t
The speed of light is
[tex]v=3\cdot 10^5\ Km/s[/tex]
It takes t=9.221 seconds for light reflected from the moon Vega to reach planet Xartan.
We can calculate the average distance the light traveled:
[tex]d=3\cdot 10^5\ Km/s*9.221[/tex]
[tex]d=2,766,300\ Km[/tex]
Or, in scientific notation:
[tex]\mathbf{d=2.77\cdot 10^6\ Km}[/tex]
