Time = distance / speed
Time = (4,800 meters) / (3 x 10⁸ m/s)
<em>Time = 0.000016 second</em>
This number is not one of the choices on the list. My hunch is that you copied the distance wrong.
If the estimated distance to the star is actually 4.8 x 10¹⁵ km, instead of 4.8 km, then the answer would be close to 500 years <em>(B)</em>.
There's no way a star can be "4.8 km away from the Earth". You can <em>walk</em> that far in about an hour, and passenger jet airplanes fly <em>twice</em> as far as that away from the Earth !
Since the mirror is plane, the image will be formed behind the mirror. The distance will be the same as that of the distance of the object from the mirror and the height will just be the same.
So, Ruff's image will be 3 m behind the mirror and 50 cm tall.
I would say B
Because technically if your just holding it your not doing anything
