Answer 1

When Sita will look into mirror her image will be at a distance of (5+5) = 10m away from her.
Geetha stands 15 m away from mirror.
Distance between Sita and Geetha = 15 - 5 = 10m
In the mirror also their image will be 10m apart.
So When Sita will look into mirror Geetha will seem to be 5+5+10 = 20m away.
