Answer

The sun's rays will be focused at the same distance from the mirror.

Work Step by Step

To find where an image forms, we can trace rays and see where the rays intersect. Since ray tracing does not depend on the index of refraction, the image forms in the same location even if the mirror is submerged in water. Therefore, the sun's rays will be focused at the same distance from the mirror.
