A long-distance truck route covers 600 kilometers. The truck travels the first 200 km at 80 km/h, the next 250 km at 100 km/h, and the remaining distance at a speed that must be determined. The driver needs an average speed of exactly 90 km/h for the entire trip to meet a delivery deadline. At what speed (in km/h) must the truck travel the final segment?
