Human Factors; Procedure
While On a VFR practice approach to RWY XX in ZZZ; traffic that we had in sight and had been advised about from ZZZ approach encroached on our final approach course; they suddenly swung under our aircraft after we crossed the final approach fix. the IP took flight controls and executed a missed approach. On the missed; we heard tower advise the other aircraft that they had lined up for the wrong runway. We climbed out uneventfully and returned to ZZZ.
I was doing another flight of practice approaches while working on my instrument rating. On this particular flight; the first approach I flew with my CFI was the RNAV approach to runway XX at ZZZ. Before getting handed off to the tower by ZZZ Approach; they point out traffic at our 10-11 o'clock and below us. My instructor had the aircraft in sight; and approach indicated that they might be talking to ZZZ tower. We then swapped to ZZZ tower and checked in on the approach; and ZZZ tower gave us no information on the amphibious aircraft that was at out 10-11 o'clock and below us. My CFI watched the traffic; and I glanced at it occasionally on ADS-B to have a general idea of where he was. About 3 miles from the runway; ADS-B indicated that the aircraft was directly below us at an altitude 200 feet lower than our altitude. At that point; my CFI took flight controls and did a rapid climb and executed the missed approach with no further conflicts; and informed ZZZ tower. While we were on the MAP; the amphibious aircraft reported a 3 mile final from runway XX; and ZZZ tower informed the amphibious aircraft that he was supposed to report a 3 mile final for runway XY.
C172 instructor and student pilots reported taking evasive action to avoid an aircraft that had lined up for the wrong runway.
