Two physics students are both farsighted. Student 1 has a near point of 66.0 cm and student 2 has a near point of 122 cm. Both students wear glasses that correct their vision to a normal near point of 25.0 cm from their eyes, and both wear glasses 2.00 cm from their eyes. The two students exchange their glasses. Determine the distance to the closest object that student 1 can clearly see while wearing student 2's glasses.
