Narrative:

Approximately 11 mi southeast of ojc, I called the tower to advise we were inbound with ATIS. While monitoring tower frequency, after being advised to enter a left downwind for runway 18, I heard tower talking to an arrow or archer who reported being 8 mi southeast preparing for a practice GPS runway 36 approach. By this time, I was 8.5 mi southeast and began looking for the other aircraft who reported to be at 3000 ft. I located the other aircraft when it was 400-500 ft and at roughly 90 degrees to my right on what appeared a collision course. I immediately hit the throttle, pulled back on the stick and believe we were able to put 200-300 ft between us vertically as the other plane passed directly beneath us. I do not believe the other aircraft saw us and I did not see any evasive action on their part. Contributing factors: my distraction inside the cockpit preparing to land, a training flight with its own inside distrs, opposing traffic instrument approach.
