Answer:

As a rough answer the crust is typically 10 to 80 km thick.

Explanation:

Clearly in some places it is much thinner (Hawaii for example, you can see lava, effectively magma, at the surface) and in others it is thicker still (beneath tall mountains.)

In miles I’d say between 6 and 40 miles with the oceanic crust being thinner on average and the continental crust being thicker.
