# Express train

International express train drove from Kosice to Teplice. In the first 279 km, the track was repaired, and therefore it was moving at a speed of 10km/h less than it was scheduled to drive. The rest of the 465 km trip has increased the speed by 8 km/h than the timetable speed. It came to Teplice for a while. Find the average speed of the train to drive according to the timetable.
