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.

Please mark the brainliest.
