$2592*10^7\frac{km}{day}$ .

Explanation:

We need to know that 1km = 1000 m= 10^3m and 1 day = 86400 = 864 * 10^2s.

$3*10^8 \frac{m}{s} = 3*10^8\frac{m}{s} \frac{86400 s}{1 day}$

$= 3*10^8*864*10^2\frac{m}{day} = 2592 * 10^{10} \frac{m}{day}$

Now, $2592 * 10^{10} \frac{m}{day}\frac{1km}{10^3m}$

$= 2592 * 10^{10}*10^{-3}\frac{km}{day} = 2592*10^7\frac{km}{day}$ .

Hey mate !

▪Magnification:-

☆Magnification produced by a spherical mirror or lens can be defined as the ratio of the height of the image to that of the object.

☆If we take h as the height of the object and h' as the height of the image, then the Magnification produced by the mirror or lens will be:-

Magnification, m = h'/h

☆The sign of the Magnification for real image is taken to be as (-)ve and it is taken as (+)ve for virtual images.

Hope it helps !
