30cm
15 from mirror then the image will be 15cm behind mirror
so 15+15
speed in air =300000km/s
refractive index
=speed in air / speed in medium
so
1.8=speed in air/speed in medium
so speed in medium
=300000/1.8
=166666.67

Here is your answer:
1) Since in a plane mirror the object distance and image distance is same therefore the image is 30cm far from tge object.
2) refractive index= c/v
1.8= 300000/v
v = 300000/ 1.8
= 166666.66km/s
Hope this the answer you wanted.
