Below is the side view of a uniformly tapering wedge. The wedge narrows uniformly towards its right end.

The thickness at the left end is 20.0 mm, and at the right end, it is 10.0 mm. The length of the wedge is 150.0 mm.

What is the thickness of the wedge at a point 60.0 mm from its narrow end?

Provide the result to an accuracy of 0.1 mm.
