Yes.
The problem states '..moves in the opposite direction at exactly the speed
that the airplane is moving
forward..' So the plane is moving forward, thus it will fly. The wheels
are just spinning at 120mph instead of the usual 60mph.

The question goes like this:

"An airplane on a runway sits on a conveyer belt that moves in the
opposite direction at exactly the speed that the airplane is moving
forward. Does the airplane take off?" (Assuming the tires hold out, of
course.)

Cecil Adams (world's smartest human being) says that it will take off
normally.
