Narrative:

The denver center 'controller' climbed aircraft Y from FL330 to FL350 at the ZMP/ZDV boundary. Aircraft X at FL350 was approximately 10 miles behind aircraft Y and 50 knots faster! We didn't notice aircraft X's airspeed until denver handed him off to us and we had already flashed aircraft Y through to ZKC. We called ZKC on the land line to alert them of the overtake and issued ZKC control. Immediately after ZKC had communications of aircraft X they turned him 20 degrees to ensure separation.apparently nothing can be done. This has gone on for 26+ years and we just have to learn to live with it. Management has turned a blind eye to it; over looked it; even snickered at it and found it amusing in the past. Nothing can be done until an accident occurs and lives are lost.
